Hence, the range is 7.
Additional information
- To find the mean, add all the values in the dataset and divide by how many there are.
- To find the median, arrange the values from least to greatest and find the number in the middle if there's an odd amount of values; if there's an even amount, then you should find the mean (average) of the two numbers in the middle.
- To find the mode, find the number that occurs the most.
