Explanation:
Mean is calculated through the average and computed as the sum of all the observed outcomes from the sample divided by the total number of events. Supposedly, if Jada's basketball team has came up with several scores during the games, the total scores are summed up through addition and divide by the number of samples. Through an example of calculation below, we can say that the sample mean of Jada's basketball team score is 44.
Example: (42 + 44 + 46) / 3 = 44
Standard Deviation shows a measure of how far the data is spread apart for a group set of data, similar idea to the distance between points. The formula of Standard Deviation is the square root of the Variance.
A low standard deviation indicates that the values tend to be close to the mean of the set, while a high standard deviation indicates that the values are spread out over a wider range. The standard deviation of 15.7 points shows that the range of scores for Jada's basketball team is close to each other.
