Questions & Step-by-Step Solutions

In a data set, if the mean is 30 and the median is 25, what can be inferred about the data?
  • 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: When the mean is greater than the median, it usually means that there are some very high numbers in the data set that are pulling the mean up.
  • Step 6: This situation indicates that the data is skewed to the right, meaning there are more lower values and a few high values.
