Questions & Step-by-Step Solutions
In a data set, if the mode is 15 and the mean is 20, what can be said about the data?
Step 1: Understand what mode means. The mode is the number that appears most often in a data set. In this case, the mode is 15.
Step 2: Understand what mean means. The mean is the average of all the numbers in the data set. Here, the mean is 20.
Step 3: Compare the mean and the mode. The mean (20) is greater than the mode (15).
Step 4: Know what positive skew means. A positively skewed data set has a longer tail on the right side, meaning there are some higher values that pull the mean up.
Step 5: Conclude that since the mean is greater than the mode, the data is positively skewed.
