Instead, we’ll measure the strength from a sample of taped boxes and use those measurements to guess what the numbers would look like if we taped a million boxes.An important point is that we won’t expect all the measurements in a group to be the same.Consider the tape example again. The differences in strength measurements from the same supplier’s tape give us within-group variation. Another important point is that we won’t expect the average strength of our sample to be the same as the average strength if we taped a million boxes. This variation between the sample average and the overall average we’ll call bias.Because of within-group variation and bias, comparisons among groups become harder. We'll know that our sample average is not the same as the real average, there’s no easy way to know when our guess is too high or too low.

Option 2: Download StatPlus:mac LE for free from AnalystSoft, and then use StatPlus:mac LE with Excel 2011.For example, if you want to know whether tapes from three different suppliers have the same peel strength, the suppliers are your factor. You can use StatPlus:mac LE to perform many of the functions that were previously available in the Analysis ToolPak, such as regressions, histograms, analysis of variance (ANOVA), and t-tests.While ANOVA has many varieties, the essential purpose of this family of analyses is to determine whether factors have an association with an outcome variable.Pycharm automatically found the installed Python interpreter.
