Answer:
Adding a constant to every score increases the mean by the same constant amount. Thus, μ
= 50+10= 60.
Adding a constant to every score has no effect on the standard deviation. σ = 5
Step-by-step explanation:
If a constant value is added to every score in a distribution, the same constant will be added to the mean. similarly, if you subtract a constant from every score, the same constant will be subtracted from the mean.
A;so recall the definition of standard deviation, it measures how each observation is far from its center on average, so if you shift your data by A then, also every observation is shifted by A and then standard deviations stays the same. also think standard deviation as measure of spread not a measure of scale.
