Explanation:

• The mean is calculated as the sum of all data values divided by the number of data values, so it is the average of all data values.
• The range is found by subtracting the smallest value from the largest value in a data - set.
• If no number occurs more than once, there is no mode (not zero).
• The mode is indeed the number (or numbers) that occurs most frequently.
• The median is the middle number when the data is arranged in numerical order.

• Range is the difference between the largest and smallest value in the set.
