### What people are saying about InStat...

"A colleague of mine said "Download InStat, you will like it." So I did, mostly so I could say, "Oh yes, I tried it." However I was not looking forward to learning a new program. Wow, was I surprised! You do not need to learn the program – it gently leads you along. It is exactly what I need in my Molecular Biology course. I do not want to spend time talking about how to slink around some convoluted program… ...I want to show [students] that statistics gives them a new way to look at the world. I think InStat will really help me do that."

"I would like to congratulate you on your excellent software InStat that is both a friendly and powerful statistical package. I have just ordered it and I am impressed with the "InStat Approach" in dealing with statistical data. I have used many statistical softwares (SPSS, SAS, Statistica, Statgraphics etc) and literally none can be considered more appropriate for a bioscientist than InStat."

"Slick interface and astonishingly intelligent way of handling the whole process of statistical testing. Very fast, very small hard disk requirement, very impressed."

"GraphPad's InStat steps students and statistical dilettantes through entering data into a spreadsheet-like table and selecting the appropriate statistical test. Just as important, InStat completes the process by explaining data analysis."

"Test results are easy to understand and include the question that is posed by the analysis, as well as unambiguous answers to the question. . . GraphPad Software continues its tradition of producing excellent documentation for its software products. . . InStat is an excellent software tool for the research lab. InStat is highly recommended, and should be the first statistical software program to use when analyzing data from the biomedical research laboratory."

"InStat is a very easy package with which to work. It is intended to provide an easy to use, basic level of statistical capability. It easily meets these criteria. It is very intuitive, includes useful Help information, and is inexpensive… For the user who needs to run only an occasional t-test, one-way ANOVA, linear regression or chi-square test, it is a good choice."

"I had a friend help me with the Multiple linear regression using SAS. Unfortunately he just sent me lots of numbers that I didn't understand. I decided to try the multiple linear regression function in Instat. The numbers came out exactly the same…and this time I understood what I was seeing. I can't thank you enough for making Instat. The instructions are easy to follow and the answers are easy to understand. And an added bonus…it doesn't take a statistics whiz to know what your getting. Great job! I'll recommend you to all my fellow graduate students."

#### InStat has all the power you need for routine statistical analyses.

"InStat, by GraphPad Software, is about the easiest statistics program I've ever seen… The program uses extensive, context-sensitive help screens to tell you what you need to know… The information is to the point, readable, and always at your fingertips… This is a program that is definitely worth considering if you have statistical needs common to the practicing clinician. It is not as powerful as some, but most of the power in the programs costing $400 or more is wasted by the typical user."

"We made the mistake of buying a more powerful and more expensive program that we were not satisfied with at all. InStat is great and so simple to use."

"InStat is a great program for the money! My lab uses it regularly."

"I am quite pleased with InStat and use it daily. Its ease-of-use makes it my program of choice over several others."

"I went through a very frustrating 1-year search using many stat packages. InStat is the only user friendly package that I found, and it performs most of the stat functions I need. I couldn't be happier. I have recommended this package to my colleagues and students."

"The InStat program is terrific! Just what bioscientists need!"

#### InStat takes just minutes to master.

"... this small, friendly software gives you instant access to statistical procedures … explains when to use which, and gives you quick clear results. ... learning to use the program literally takes no longer than the time needed to install it, about 45 seconds. I was entirely charmed by the simple thoroughness of this package. The range of procedures, ease of use and sound explanations of theory make it an ideal addition to laboratory software."

"InStat was deliberately designed to lead a user logically through each step of the data-analysis process, from entering data to viewing (and understanding) the results. In fact, although most statistics packages do not give users any guidance about entering data, getting data into the computer in the correct format goes a long way toward simplifying the analysis process to follow."

"I'm very pleased with InStat. In contrast to my previous experiences, now it is a pleasure (not a chore) to perform statistical analysis."

"Quick, easy to use, effective. Easy to train student to analyze data."

"Appreciate the ease of use — good explanations."

#### InStat can be the perfect complement to a more complex program.

"I've been using SAS, but InStat really suits most of my needs and is a lot easier to use."

"InStat is a wonderful program for my student research fellows. I also use it (prefer it) for small data sets rather than SPSS."

"Most popular program in the lab. Preferred over Systat and Abstat."

#### InStat is designed for scientists and students, not statisticians.

"I tested a number of statistics packages for possible use in the course. My standard test was to start with a set of data and try to analyze it without ever looking at the software documentation. If I had to look up something, then that meant the students would have to waste their time when they tried to use it. InStat was the only package that passed the test. I could completely analyze my data and, as an added bonus, develop a lot of insight into the results, all in just a few minutes. InStat has now received a complete testing during our eight-week course in which each of 22 students completed five projects, all requiring statistical analysis. InStat helped students who had just learned about inferential statistics in classrooms to feel comfortable using those tests on real data they collected in the course. The process of logically thinking through the different steps, aided by InStat's suggested analyses and interpretations, gives students a solid foundation in data analysis and interpretation that they will use for the rest of their careers."

"Excellent service — InStat makes statistical analysis friendly for us non-statisticians."

"InStat is a really great program, very easy to use. I wish I'd had it years ago!"

"Great program, a pleasure to use! Help screens are great!"

"I've learned more statistics using your program than I did in graduate school!"
