If someone scored two Standard Deviations above the Mean on a standardized test where the Mean = 100 and the Standard Deviation = 15, then that person’s numerical score would be…?
130
To calculate the numerical score, we need to apply the concept of standard deviation to the given information.
Given:
Mean = 100
Standard Deviation = 15
Number of Standard Deviations above the Mean = 2
To calculate the numerical score, we can use the formula:
Numerical score = Mean + (Number of Standard Deviations × Standard Deviation)
Substituting the values we have:
Numerical score = 100 + (2 × 15)
Numerical score = 100 + 30
Numerical score = 130
Therefore, the person’s numerical score would be 130.
