QuickStat is a fast statistics application that instantly provides you with the results for a number of common statistical tests. It is designed for small data sets and it features fast data entry and automatic comparative analysis of data in one or two groups. Data is saved between uses and if desired, data can be saved to files.
On the main data entry screen, mean and standard deviation is dynamically calculated as data is entered. Touch the “Stats” button to see mean, standard deviation, standard error of the mean, and probability of those means tested against a mean of your choosing. If there are more than 3 data entries per group, the “Stats” page also displays the average of the ratio of the data points (paired), the unpaired and paired differences and the Pearson correlation coefficient. Probabilities are also calculated for each of these statistics.
In addition, if there is sufficient data in each group, a linear fit is done and you may enter any “x” value to see the predicted “y” based on the linear fit.
Want to see how the data looks? Touch the “Plot” button and a simple plot for both groups of data and for ‘group 1’ vs. ‘group 2’ is shown. Estimated sampling distributions are also shown and a visual representation of the p-value for the expected mean entered by you.
Data entries can also be masked from the calculations, allowing quick “what-if” testing.
- Very fast data entry for each column
- Keyboard remains present between data entries
- All statistics calculated automatically
- Line fit predictions
- Automated data plotting
- User entered mean testing
- Data masking
- Data recalled between uses
- Data saving

Very good and simple to use. I've been looking for a statistic calculator, but this one is simple and to the point.

I have been looking for a basic app that can help with quick calculations and plots on the fly in the field. QuickStat meets that and more. I appreciate the work that the developers have put into this already and will look for more from them.
