Online calculator and plot generator for reliability and validity
The calculator below generates absolute (abs) and relative (rel) intraclass correlation coefficient (ICC) for model types 2,1 and 2,k, percentage based minimum detectable change (MDC) and standard error of the measurement (SEM) scores for two columns of data. It also generates a scatterplot with linear fit and confidence intervals, standard and linear regression based Bland and Altman plots and histograms with normal distribution shading for the datasets.
To use it simply paste one column of data (300 rows maximum) from a spreadsheet program like Excel into the first column, and repeat in the second column. The first row in each column should be the heading you want displayed on the graphs - refer to the default column layout if you are unsure. Then click the green process button and it's done. You can then either print the page as a pdf file or do a screen print for editing the figures.
None of your data or interactions are saved, and noone can see what you are doing other than people looking at your screen.

Exporting to Excel
Download the .xlsx file below as a template if you want to copy and save the results of this page. Simply open the template, then for each analysis copy all of the data from the "Results - Excel Ready" box and paste it into the first column. You can also screenshot the graphs, either by a simple print screen command or preferably using something like the snippet tool in Windows.
