2. The "mean" is the "average" you're used to, where you add up all the numbers and then divide by the number of numbers. Eddie Alvarez

3. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. Anna perales The cost of a tank of gas at nine different gas stations is shown below. What was the mean cost of a tank of gas? Cost of Gas: $17, $18, $22, $15, $17, $16, $25, $21, and $20 25+22+21+20+18+17+17 +16=156 8 156= 19.4

4. The median number is the number that falls directly in the middle of the list.

5. To find the median, the data should be organized into sequential order. The middle value in the sequence in the median, for example in the sequence 3,6,9, 6 would be the median. Marco soto 3, 5, 7, 12, 13, 14, 21, 23, 23, 23, 23, 29, 39, 40, 56.The median value of this set of numbers is 23.

6. The "mode" is the value that occurs most often. Marco Soto

7. The number repeated most often. This list has two values that are repeated three times. Chantz skaer {8, 15, 19, 19, 28, 29, 35}19 appears twice, all the rest appear only once, so 19 is the mode Kate seen 8 blue car, 15 red cars, 19 pink cars, 19 brown cars, 28 white cars, 29 green cars, and 35 black cars

8. The "range" is just the difference between the largest and smallest values Chantz skaer

9. Just order the data from least to greatest, find the lowest and highest numbers in that set, and then subtract the lowest number from the highest number. Mariela Ramirez 13, 18, 13, 14, 13, 16, 14, 21, 13The mean is the usual average, so:(13 + 18 + 13 + 14 + 13 + 16 + 14 + 21 + 13) ÷ 9 = 15
