Answer :
The statistic that would not change if 50 points were added to each score in the SAT tests is the Standard Deviation.
What happens to the standard deviation ?
The square root of the variance is used to calculate the standard deviation, a statistic that expresses how widely distributed a dataset is in relation to its mean. By calculating the deviation of each data point from the mean, the standard deviation may be determined as the square root of variance.
The bigger the deviation within the data collection, the further the data points deviate from the mean; hence, the higher the standard deviation, the more dispersed the data.
Since they are used to determine standard deviation, sample size, mean, and data values all have an impact on standard deviation. By removing outliers, the sample size, mean, and standard deviation may all change.
Because 50 points was added to each score, they are still the same distance from each other which means the standard deviation will not change.
