What is the grand average of the subgroup averages?
The grand average of the subgroup averages is calculated by taking the mean of all subgroup averages. This involves summing all the subgroup averages and then dividing by the number of subgroups. It provides a single representative value that reflects the overall average performance or characteristics of the entire set based on the individual subgroup averages. This approach is often used in statistical analysis to summarize data effectively.
Is a sum of averages accurate?
No, a sum of averages is NOT as accurate as the average of the whole. For example: A=avg (1,10) = 5.5 B=avg (1, 1, 1, 1, 1) = 1 avg(A,B) = 3.25 [Average of averages] avg(1,1,1,1,1,1,10) = 2.29 [The original data set]
Why cant you average an average?
You can't average an average because averages are calculated based on specific data sets, and combining them without considering the underlying sample sizes can lead to misleading results. For instance, if you average the average test scores of two classes with different numbers of students, you may not accurately represent the overall performance. To properly combine averages, you need to weight them according to the size of their respective data sets.
