Question
A researcher wants to express the spread of scores from the mean of a data set in the same scale as the original variable. Which of the following is the appropriate measure?1 pointRangeVarianceMedianStandard deviation
Solution 1
The appropriate measure for expressing the spread of scores from the mean of a data set in the same scale as the original variable is the Standard deviation. This is because the standard deviation is a measure of the amount of variation or dispersion of a set of values. 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. It is expressed in the same units as the original data, which makes it a suitable measure for this purpose.
Solution 2
The appropriate measure for expressing the spread of scores from the mean of a data set in the same scale as the original variable is the Standard deviation. This is because the standard deviation is a measure of the amount of variation or dispersion of a set of values. A low standard deviation
