The document discusses statistical measures including frequency, cumulative frequency, mean, median, and mode. It provides examples of calculating each measure using various data sets. The mode is defined as the number that occurs most frequently. The median is defined as the middle number when values are ordered from lowest to highest. The mean is defined as the total of all values divided by the number of values.

3. Mode: the number you see occur the most often. Goals scored by Cory last year: 0,1,1,3,2,5,1,0,1 Mode:1 (four times) Miles Ashley ran last week: 3,5,7,5,2,3,5 Mode: 5 (three times) Points scored by Corissa in basketball: 0,10,0,10,0,10,4 Mode: 0 and 10 (three times each)

4. Median: The middle number in a set of data. Example A: 1,3,5,7,9- Median is 5 Hint: Always rewrite the numbers from least to greatest to make it easier to find the median. Example B: 2,4,6,8- There are two middle numbers (4 and 6) so you find what number is right between them (answer-5) Set 1: 12, 12, 7, 9, 10 Rewrite: 7, 9, 10, 12, 12 Median: 10 Set 2: 4,2,4,4,2,2 Rewrite: 2, 2, 2, 4, 4, 4 Median: 3 Set 3: 54, 53, 56, 54, 55 Rewrite: 53, 54, 54, 55, 56 Median: 54

5. Mean: The average, add all of the numbers in a set and divide by how many numbers are in the set. Example: 3,4,1,4,3 3 + 4 + 1+ 4 + 3=15 There are 5 numbers 15÷5= 3

6. Find the mean, median, and mode. Mean: 5 Median: 5 Mode: no mode Day 1 2 3 4 5 Baskets 5 7 6 4 3

7. Find the mean, median, and mode. Mean: 10 Median: 10 Mode: 12 Student Ann Bob Carl Dan Ed Age 9 10 7 12 12
