Question

the population variances for each of the treatment groups are equal. the values of the repeated variables are constant. the populations from which the samples were taken are normally distributed. the treatment effect is consistent for all subjects.

Answer 1

If all viable observations of the device are present then the calculated variance is referred to as the populace variance. normally, however, most effective a subset is to be had, and the variance calculated from that is called the sample variance.

Population variance is a degree of ways unfold out a collection of information points is. particularly, it quantifies the common squared deviation from the imply. So, if all data factors are very close to the imply, the variance could be small; if records factors are spread out over a wide variety, the variance can be large.

The variance is a measure of variability. it is calculated by means of taking the common of squared deviations from the suggest. Variance tells you the degree of unfold in your information set. The more unfold the statistics, the larger the variance is in relation to the suggest.
