Geoffrey It's looking at 2 letters each of which has the same mean.How can he determine which of the two datasets has less Variability, A the dataset with less variability, has greater deviation.B the dataset with more pieces of data.Will have less variability C The data sets have the same variability.Because their means are the same D, the data set with less variability has a smaller deviation.
D, the data set with less variability has a smaller deviation.
Variability is a measure of how spread out the data points are in a dataset. A smaller deviation indicates that the data points are closer together and therefore less spread out, leading to less variability. So, in this case, Geoffrey can determine that the dataset with less variability will have a smaller deviation.
