![]() Enter the data from the above Nonsmokers sample table in the first Strata tab (Strata 1). A blank table opens in the StatCalc application window. • Right click and select the Save as Image option to save a screen shot of your results as an image file. To view and create a Stratified Analysis Summary of 2-by-2 Tables, take the following steps: From the StatCalc application main page, select Tables <2 x 2, 2 x n>.Right click and select the Print option in order to print the results.You can also select calculations by pressing the corresponding key on the keyboard that matches the highlighted letter on the menu. StatCalc is also one of the easiest tools to use. Select one of the following calculations using the up and down arrow keys or click: Sample Size & Power, Chi Square for Trend, Tables (2X2, 2Xn), Poisson (rare event vs. You input your parameters such as expected outcome value and desired precision, and then StatCalc determines the sample size. To modify values already entered, use the Tab key or click on the cell and enter the new information. No memorization of formulas or mathematical equations is necessary StatCalc has several tools: Sample Size and Power, Chi Square for Trend, and Tables (2X2, 2XN).Calculations are performed when you enter data. Use the tab key or return key to move around the different cells available for data entry.If you select the Sample size and power calculation, the following calculation options appear: Population Survey, Cohort or Cross-Sectional, Unmatched Case-Control.If you select a calculation using the keyboard, the calculation appears immediately. Please enter the necessary parameter values, and then click 'Calculate'. You can also select calculations by pressing the corresponding key on the keyboard that matches the highlighted letter on the menu. This calculator will compute both the exact hypergeometric probability and the exact two-tailed probability of obtaining a distribution of values in a 2x2 contingency table using Fisher's exact test, given the number of observations in each cell.Select one of the following calculations using the up and down arrow keys or click: Sample Size & Power, Chi Square for Trend, Tables (2X2, 2Xn), Poisson (rare event vs.From the Epi Info 7 main menu, select StatCalc.It doesn't require heavy experience with statistical software, so it can be figured out by casual and advanced users alike. Taking into account its intuitive and practical options, StatCalc comes in handy to all users looking for a simple and effective way to perform statistical calculations. OpenEpi provides statistics for counts and measurements in descriptive and analytic studies, stratified analysis with exact confidence limits, matched pair and person-time analysis, sample size and power calculations, random numbers, sensitivity, specificity and other evaluation statistics, R x C tables, chi-square for dose-response, and links. It used low CPU and RAM, so it didn't hamper system performance. We haven't come across any stability issues in our tests, thanks to the fact that the app didn't hang, crash or display error dialogs. The output viewer lets you make a text selection to copy the statistics to the Clipboard.įurthermore, StatCalc implements options for importing and exporting tab-delimited and comma-delimited files, as well as for printing output data. When it comes to decision tools, you can create decision tables, perform a queuing analysis, check out constant dollars, or calculate price elasticity. ![]() All you have to do is enter the necessary data. ![]() ![]() You can explore and perform calculations within a multitude of procedures, such as frequencies, descriptives, weighted mean, diagnostic accuracy, goodness of fit, correlation, along with OLS or logistic regression. Clear-cut interfaceĪfter a brief and uneventful setup operation, you are welcomed by a user-friendly interface which consists from a normal window with a plain and simple structure split into three tabs dedicated to statistical tools, decision utilities, and the output viewer, respectively. This calculator will compute both the exact hypergeometric probability and the exact two-tailed probability of obtaining a distribution of values in a 2x2 contingency table using Fisher's exact test, given the number of observations in each cell. It offers support for decision tools and an output viewer. Fisher's Exact Test Calculator for a 2x2 Contingency Table. StatCalc is a comprehensive, yet simple-to-use software utility that enables you to perform and compare statistical calculations. ![]()
