If the mean of the data set is 4. Then the standard deviation will be 2.45.
What is Mean?
The mean is the straightforward meaning of the normal of a lot of numbers. It's the proportion of the number of genuine perceptions to the absolute number of perceptions.
The data set is given in the diagram.
Then the mean of the data set will be
Mean = (8 + 5 + 4 + 2 + 1) / 5
Mean = 20 / 5
Mean = 4
Then the standard deviation will be
SD = √{[(8 - 4)² + (5 - 4)² + (4 - 4)² + (2 - 4)² + (1 - 4)²] / 5}
SD = √{(16 + 1 + 4 + 9) / 5}
SD = √{30 / 5}
SD = √6
SD = 2.45
