GraphPad Prism


GraphPad Prism, available for both Windows and Mac computers,  combines scientific graphing, comprehensive curve fitting (nonlinear regression), understandable statistics, and data organization.
GraphPad Prism was originally designed for experimental biologists in medical schools and drug companies, especially those in pharmacology and physiology. Prism is now used much more broadly by all kinds of biologists, as well as social and physical scientists.  More than 200,000 scientists in over 110 countries rely on Prism to analyze, graph and present their scientific data. It is also widely used by undergraduate and graduate students.

Nonlinear regression

Nonlinear regression is an important tool in analyzing data, but is often more difficult than it needs to be. No other program simplifies curve fitting like Prism. In fact, you can usually fit curves in a single step. Just select an equation from the extensive list of commonly used equations (or enter your own equation) and Prism does the rest automatically — fits the curve, displays the results as a table, draws the curve on the graph, and interpolates unknown values.
Place data for multiple data sets side-by-side on an organized data table, and Prism can fit them all the data sets at once. You can fit the same model separately to each data set, use global nonlinear regression to share parameter values among data sets, or fit different models to different data sets.
Don’t be fooled by the simplicity. Prism also gives you many advanced fitting options. It can automatically interpolate unknown values from a standard curve (i.e., to analyze RIA data), compare the fits of two equations using an F test or Akaike’s Information Criterion (AIC), plot residuals, identify outliers, differentially weight data points, test residuals for normality, and much more.

Understandable statistics

While it won’t replace a heavy-duty statistics program, Prism lets you easily perform basic statistical tests commonly used by laboratory and clinical researchers. Prism offers t tests, nonparametric comparisons, one- and two-way ANOVA, analysis of contingency tables, and survival analysis. Analysis choices are presented in clear language that avoids unnecessary statistical jargon.
Unlike other programs, Prism provides understandable statistical help when you need it. Press “Learn” from any data analysis dialog and Prism’s online documentation will explain the principles of the analysis to help you make appropriate choices. Once you’ve made your choices, Prism presents the results on organized, easy-to-follow tables. The Prism documentation goes beyond anything you would expect. More than half of it is devoted to thorough explanations of basic statistics and nonlinear curve fitting, to teach you what you need to know to appropriately analyze your data.

Analysis checklists

Once you’ve completed the analysis, Prism’s unique analysis checklists help you make sure you chose an analysis appropriate for your experimental design, and that you understand the assumptions behind the analysis.

Retrace every analysis

It isn’t really science unless you can document exactly how your data were analyzed. WIth Prism this isn’t a problem. You’ll never wonder how the results got there. Even if the work was done by someone else, you can review (and change) all analysis choices, and see the sequence of analyses (i.e. that the X values were transformed to logarithms before the curve was fit). Similarly, you can easily check if error bars represent the SD or SEM (or something else).

Automation without programming

All parts of your Prism project are linked. This means that when you fix a data entry error, Prism automatically updates all results, graphs, and layouts. Another advantage is that you can instantly analyze a repeat experiment. After you’ve polished the analysis and graphing steps with data from one experiment, you don’t have to repeat all those steps. Prism provides several ways to recycle your work — to instantly analyze and graph a repeat experiment, without repeating any tedious steps and without requiring any scripting or programming.

After taking courses in statistics, and reading textbooks of statistics, you may still find statistics confusing. What you need is not more information, but rather advice, perspective, and a guide to steer you away from data analysis traps. These three books provide what you need. All three are written for people who already have learned the basics of statistics, but are still struggling with practical issues of data analysis. All three are extremely well written in plain English (without much math), and are quite accessible to scientists. I strongly recommend all three books. Choosing between them is hard, as all three are great. The best way to choose is to read excerpts online.Read More >
Making sense of ANOVA
Analysis of Variance (ANOVA) is a powerful technique in statistics, but one that can be quite confusing and is often abused. If you want to really understand ANOVA, this clearly written book will help. It explains ANOVA from the perspective of comparing the fit of alternative models, rather than the more conventional approach of dividing variation into its components. It has plenty of math, but explains all concepts in plain English.Read More >
An in-depth guide to dose response curves
While overkill for most pharmacologists, this is a unique resource for people who need to deal with complex dose-response relationships, including allosteric interactions, synergy, multi-step binding, cubic binding models and much more. It deals only with systems at equilibrium, so does not cover kinetics. If you are curious, start with this chapter, which explains many variations on the Hill equation, and the many uses of the term “logistic”. If you haven’t heard of the Hill equation, this book is not for you!Read More >

10 Chrome extensions to help manage references, notes, citations and capture information.

From literature searches to collaborative online writing, a significant amount of the research process now takes place online. Andy Tattersall provides a list of useful Google Chrome extensions that can be added to the browser to help facilitate the daily academic workflow. Recommendations below cover tools for reference management, link saving, and finding quick access to academic articles.
Not everyone uses Google Chrome as their browser of choice, some can’t install it, others can’t get on with it and there are probably a few who still do not realise it exists. Whilst Chrome has a wealth of good reasons why you should use it, from syncing your accounts across devices to its search functionality; there are other reasons why you should consider Chrome. These are called extensions which you can install to improve your web experience even more. There are a growing number of useful extensions for the digital academic, of which I have picked 10 of the best below. I’ve also given the Chrome Store average review and how many copies of each extension has been installed, as a broad indicator of popularity and uptake.
Readability is a tool I’ve promoted on countless occasions thanks to ability to turn complicated, image and link-heavy web pages into simple, clean PDF type documents. By clicking this extension whilst viewing a webpage you can read the article free of distraction or save it later to read offline on your computer or tablet.
Chrome Web Store Rating 4 /5 – 583k users

Evernote is a bit of a Swiss Army Knife of an extension. Not only does it do something very similar to Readability and clean up web pages for later viewing but it also captures the web page in full with its Web Clipper tool. You can also take screenshots, save articles and bookmark pages to your Evernote scrapbook.

If you are making a presentation, poster or writing something that requires a URL it’s important to make those links as easy to copy and access as possible. Very often presentations link to external artefacts, or give copyright attributions that have a URL so long and complicated that only the most eagle-eyed will be able to write it down before the presentation moves on. The button turns the long URL into something much more digestible, as well as make it useful for anyone Tweeting the link and wanting to save on character space.

Taking screenshots can be a laborious task and often resulted in hitting the ‘Print Screen’ button followed by cropping the outer content in Paint (when you could find it), PowerPoint or some other tool. Nimbus Screenshot is one of many similar tools that allows capture and crop all directly from the browser. Cropped content can be edited and annotated before being saved locally to your computer.
Chrome Web Store Rating 41/2 / 5 – 257k users
An interesting and inventive extension to say the least. Lazy Scholar gives users a snapshot of metrics relating to a piece of research. It can be hit and miss at times but is worth trying out to see what data it retrieves. By clicking on the extension in sites such as Pubmed the Lazy Scholar toolbar pops up giving information on Scholar Cites, Web of Science score, Altmetric score, Journal Impact Factor, as well as contact email and whether there have been any comments on the paper.

This works with Google Scholar and turns search results into easy copy and paste references using the main styles of APA, MLA and Chicago. The extension also allows you to track down PDFs of the paper and export results in a variety of formats that can be used in reference management packages.

This is an extension for Twitter that mirrors your Twitter experience and allows you to follow your timelines, compose Tweets, share, delete and favourite them. It automatically creates short URLs within the extension and acts as a notifier for new Tweets.
Chrome Web Store Rating 4.5/5 – 280k users
Unlike the other extensions in this list, PaperPile isn’t free but comes with a 30 day free trial so at least you can decide whether it is useful. PaperPile is a reference management tool for researchers and students who rely on Google Apps to carry out their research. One of the flaws in the Google education model has been the lack of a good, solid reference management tool. Tools like Mendeley, Zotero and Endnote are quite comprehensive and rightly so as accurate and thorough referencing in academia is important. So whether this extension can match these established tools, only time will tell. Nevertheless it is worth investigation for Chrome based researchers.
Chrome Web Store Rating 5/5 – 2k users

Another citation tool to investigate alongside the excellent EasyBib and RefMe ones that are also worth looking at. Cite This For Me can create references in APA, Chicago, Harvard and MLA formats and provides a pop-up box containing the appropriately formatted reference for  books, newspapers, journals and more. I tried it with a BBC football story and it worked fine, allowing me to switch between citation styles. It gives the option of adding to your Cite This For Me bibliography or exporting to a piece of research.

After a while you might start to notice whilst having multiple Chrome tabs open that your computer struggles with performance. Obviously having multiple tabs open is going to use valuable computing resources. Having lots of extensions running can also be at the detriment of your computing experience. Therefore it becomes increasingly important to have an extension to manage your extensions, especially when you accrue so many, some of which you may have stopped using.

Statistical Package for the Social Sciences (SPSS)

For many students, the thought of completing a statistics subject, or using statistics in their research, is a major source of stress and frustration. The aim of the original SPSS Survival Manual (published in 2000) was to provide a simple, step-by-step guide to the process of data analysis using SPSS. Unlike other statistical titles it did not focus on the mathematical underpinnings of the techniques, but rather on the appropriate use of SPSS as a tool. Since the publication of the three editions of the SPSS Survival Manual, I have received many hundreds of emails from students who have been grateful for the helping hand (or lifeline). The same simple approach has been incorporated in this fourth edition. Since the last edition, however, SPSS has undergone a number of changes—including a brief period when it changed name. During 2009 version 18 of the program was renamed PASW Statistics, which stands for Predictive Analytics Software. The name was changed again in 2010 to IBM SPSS. To prevent confusion I have referred to the program as SPSS throughout the book, but all the material applies to programs labelled both PASW and IBM SPSS. All chapters in this edition have been updated to suit version 18 of the package (although most of the material is also suitable for users of earlier versions).I have resisted urges from students, instructors and reviewers to add too many extra topics, but instead have upgraded and expanded the existing material. This book is not intended to cover all possible statistical procedures available in SPSS, or to answer all questions researchers might have about statistics. Instead, it is designed to get you started with your research and to help you gain confi dence in the use of the
program to analyse your data. There are many other excellent statistical texts available that you should refer to—suggestions are made throughout each chapter in the book. Additional material is also available on the book’s website (details in the next section).
