When we talk about model variance in the analysis of variance, we are talking about:Question 7Answera.the overall variability of scores in the datasetb.differences between participants across different groupsc.the misrecording of datad.differences between participants within the same group
Solution
When we talk about model variance in the analysis of variance, we are referring to the overall variability of scores in the dataset. This is because variance in statistics is a measurement of the spread between numbers in a data set. More specifically, it measures how far each number in the set is from the mean (average) and thus from every other number in the set. Model variance in the analysis of variance is therefore concerned with the overall variability of scores in the dataset.
