Question

The daily way just paid the fiber are 25, 40, 65,55 and 50. What is the main absolute deviation of the data set

Answer 1

The mean absolute deviation (MAD) of the data set (25, 40, 65, 55, and 50) is calculated by finding the average of the absolute deviations of each data point from the mean of the set. The mean of the set is 47, and the MAD is 11.6.

Step-by-step explanation:

The question appears to be asking about the mean absolute deviation (MAD) of a data set. The data set provided is: 25, 40, 65, 55 and 50. To calculate MAD:

1. Find the mean (average) of the data set.
2. Calculate the absolute deviation of each data point from the mean by subtracting the mean from each point and taking the absolute value.
3. Average these absolute deviations to find the MAD.

Step 1: Calculate the mean:
Mean = (25 + 40 + 65 + 55 + 50) / 5 = 235 / 5 = 47

Step 2: Calculate absolute deviations:
(|25 - 47|) + (|40 - 47|) + (|65 - 47|) + (|55 - 47|) + (|50 - 47|) = 22 + 7 + 18 + 8 + 3 = 58

Step 3: Calculate the MAD:
MAD = total of absolute deviations / number of data points
MAD = 58 / 5 = 11.6

The mean absolute deviation of the data set is 11.6.
