Means and Std Deviations Report

In the Oneway platform, the Means and Std Deviations report contains summary statistics for each level of the X variable. The levels of the X variable define groups, or treatments.

Level

The levels of the X variable.

Number

The number of observations in each group.

Mean

The mean of each group.

Std Dev

The standard deviation of each group.

Std Err Mean

The estimates of the standard error for the group means. This value is the standard deviation divided by the square root of the number of values used to compute the group mean.

Lower 95% and Upper 95%

The lower and upper 95% confidence interval for the group means based on the standard deviations and sample sizes.

Note: These confidence intervals differ from the ANOVA confidence intervals, especially when the standard deviations of each group are different.
