Find the average of the distribution given below.
Value Percent of entries
-16 10
-3 25
5 45
8 20
To find the average of a distribution, you need to multiply each value by its corresponding percent of entries, then sum up those values and divide by 100. Let's calculate the average step by step.
1. Multiply each value by its percent of entries:
-16 * 10 = -160
-3 * 25 = -75
5 * 45 = 225
8 * 20 = 160
2. Sum up the values:
-160 + (-75) + 225 + 160 = 150
3. Divide the sum by 100:
150 / 100 = 1.5
The average of the distribution is 1.5.
