Calculation of Mean from Deviations
Given:
- Sum of deviation from 13 = 74
- Sum of deviation from 17 = 26
We know that the mean can be calculated as:
Mean = (Sum of observations) / (Number of observations)
We can also calculate the mean from deviations as:
Mean = (Sum of deviations) / (Number of observations)
Calculating Number of Observations
To calculate the mean from deviations, we need to first calculate the number of observations. We can do this by using the fact that the sum of deviations from the mean is always zero.
Sum of deviations from 13 + Sum of deviations from 17 = 0
74 + 26 = 100
This means that the total number of observations is:
Number of observations = Sum of deviations / Deviation from the mean
Number of observations = 100 / (17 - 13) = 25
Calculating Mean from Deviations
Now that we know the number of observations, we can calculate the mean from deviations:
Mean = (Sum of deviations) / (Number of observations)
Mean = (74 + 26) / 25
Mean = 100 / 25
Mean = 4
Therefore, the mean of the observations is 4.
