Question

find the mean of the follwing data set:
12, 0, 8, 4, 6, 3, 7, 3, 2, 9, 5, 6, 7, 7, 8
□ 6
□ 5.8
□ 7
□ 6.5
question 4
find the mode of the follwing data set:
12, 0, 8, 4, 6, 3, 7, 3, 2, 9, 5, 6, 7, 7, 8
□ 6
□ 5.8
□ 7
□ 6.5

Explanation:

Step1: Sum all data values

$12+0+8+4+6+3+7+3+2+9+5+6+7+7+8 = 87$

Step2: Count total data points

$n=15$

Step3: Calculate the mean

$\text{Mean} = \frac{87}{15} = 5.8$

Step4: Identify the mode

Count frequency of each value: 3 appears 2 times, 6 appears 2 times, 7 appears 3 times, others appear once. The most frequent value is 7.

Answer:

Question 3: 5.8
Question 4: 7
