Answer:
Step-by-step explanation:
One of the method of analysing the distribution of a dataset is by finding the mean of the dataset which is part of the measure of central of tendency.
Mean of a dataset is also known as the average and it is the ratio of the sum of the individual dataset to the sample size.
Mathematically xbar = ΣXi/N where
ΣXi is the sum of the individual dataset
N is the sample size
xbar is the mean
From the formula, ΣXi = xbar * N
This means that the sum of the individual dataset (all values in the dataset) is equal to the product of the mean (xbar) and the sample size(N).
Hence the statement that In any sample data set, the sum of all the values is equal to the product of the mean and the sample size."is TRUE
