ANSWER:
Mean: 98.1
Mode: 99
Range: 7
MEAN:
95 x 1 = 95
96 x 2 = 192
97 x 4 = 388
98 x 4 = 392
99 x 7 = 693
100 x 1 = 100
101 x 0 = 0
102 x 1 = 102
95 + 192 + 388 + 392 + 693 + 100 + 0 + 102 = 1962
1 + 2 + 4 + 4 + 7 + 1 + 0 + 1 = 20
Step 4: Divide the sum from Step 2 by the sum from Step 3.
1962 / 20 = 98.1
mean= 98.1.
MODE:
The highest frequency is 99, which appears 7 times. So 7.
RANGE:
Range = Highest value - Lowest value
Range = 102 - 95
Range = 7
ANSWER:
Mean: 98.1
Mode: 99
Range: 7
