The mean is affected by extreme values because it takes into account all values in the data set.
A scatter plot shows how two variables relate to each other, often revealing correlations.
The mean is calculated by summing all the values and dividing by the total number of values.
The median is the middle value of an ordered data set. Here, 9 is the middle value.
The range measures the spread of the data by subtracting the smallest value from the largest value.
