Mean, Mode, Median and Range interactive worksheet - Free Printable

Let’s solve each set of data step by step. We’ll find the mean, median, mode, and range for each group.

First Set: 2, 7, 4, 2, 3, 6, 11

Step 1: Mean
Add all numbers: 2 + 7 + 4 + 2 + 3 + 6 + 11 = 35
Count how many numbers: 7
Mean = 35 ÷ 7 = 5

Step 2: Median
Put in order: 2, 2, 3, 4, 6, 7, 11
Middle number (4th one) = 4

Step 3: Mode
Which number appears most? → 2 (appears twice)

Step 4: Range
Highest - Lowest = 11 - 2 = 9

✔ Answers:
MEAN: 5
MEDIAN: 4
MODE: 2
RANGE: 9

Second Set: 11, 4, 7, 8, 2, 6, 4

Step 1: Mean
Add: 11 + 4 + 7 + 8 + 2 + 6 + 4 = 42
Count: 7
Mean = 42 ÷ 7 = 6

Step 2: Median
Order: 2, 4, 4, 6, 7, 8, 11
Middle = 6

Step 3: Mode
Most frequent = 4 (twice)

Step 4: Range
11 - 2 = 9

✔ Answers:
MEAN: 6
MEDIAN: 6
MODE: 4
RANGE: 9

Third Set: 70, 63, 67, 62, 63

Step 1: Mean
Add: 70 + 63 + 67 + 62 + 63 = 325
Count: 5
Mean = 325 ÷ 5 = 65

Step 2: Median
Order: 62, 63, 63, 67, 70
Middle = 63

Step 3: Mode
Most frequent = 63 (twice)

Step 4: Range
70 - 62 = 8

✔ Answers:
MEAN: 65
MEDIAN: 63
MODE: 63
RANGE: 8

Fourth Set: 14, 68, 38, 65, 36, 57, 65

Step 1: Mean
Add: 14 + 68 + 38 + 65 + 36 + 57 + 65 = 343
Count: 7
Mean = 343 ÷ 7 = 49

Step 2: Median
Order: 14, 36, 38, 57, 65, 65, 68
Middle = 57

Step 3: Mode
Most frequent = 65 (twice)

Step 4: Range
68 - 14 = 54

✔ Answers:
MEAN: 49
MEDIAN: 57
MODE: 65
RANGE: 54

Fifth Set: 109, 104, 96, 103, 104, 107, 98

Step 1: Mean
Add: 109 + 104 + 96 + 103 + 104 + 107 + 98 = 721
Count: 7
Mean = 721 ÷ 7 = 103

Step 2: Median
Order: 96, 98, 103, 104, 104, 107, 109
Middle = 104

Step 3: Mode
Most frequent = 104 (twice)

Step 4: Range
109 - 96 = 13

✔ Answers:
MEAN: 103
MEDIAN: 104
MODE: 104
RANGE: 13

Sixth Set: 22, 37, 19, 25, 37, 51, 82

Step 1: Mean
Add: 22 + 37 + 19 + 25 + 37 + 51 + 82 = 273
Count: 7
Mean = 273 ÷ 7 = 39

Step 2: Median
Order: 19, 22, 25, 37, 37, 51, 82
Middle = 37

Step 3: Mode
Most frequent = 37 (twice)

Step 4: Range

Seventh Set: 32, 37, 35, 34, 25, 41, 34

Step 1: Mean
Add: 32 + 37 + 35 + 34 + 25 + 41 + 34 = 238
Count: 7
Mean = 238 ÷ 7 = 34

Step 2: Median
Order: 25, 32, 34, 34, 35, 37, 41
Middle = 34

Step 3: Mode
Most frequent = 34 (twice)

Step 4: Range
41 - 25 = 16

✔ Answers:
MEAN: 34
MEDIAN: 34
MODE: 34
RANGE: 16

Eighth Set: 126, 128, 107, 113, 120, 126

Step 1: Mean
Add: 126 + 128 + 107 + 113 + 120 + 126 = 720
Count: 6
Mean = 720 ÷ 6 = 120

Step 2: Median
Order: 107, 113, 120, 126, 126, 128
Two middle numbers: 120 and 126 → average = (120 + 126) ÷ 2 = 123

Step 3: Mode
Most frequent = 126 (twice)
