Q: In a data set, if the mean is 30 and the median is 25, what can be inferred?
Solution: Since the mean is greater than the median, the data is skewed to the right.
Steps: 6
Step 1: Understand what the mean is. The mean is the average of all the numbers in the data set.
Step 2: Understand what the median is. The median is the middle number when all the numbers are arranged in order.
Step 3: Compare the mean and the median. In this case, the mean is 30 and the median is 25.
Step 4: Notice that the mean (30) is greater than the median (25).
Step 5: Recognize that when the mean is greater than the median, it often indicates that there are some larger values in the data set that are pulling the mean up.
Step 6: Conclude that the data is likely skewed to the right, meaning there are some high values that affect the average.
