Question

You have a data set C1 and you do the following transformation using statistical software: C2=C1/5

You find the mean, median and standard deviation of the original C1 and the new C2 and compare them.

You must then answer the question pictured below. I assumed "none of them" would be the answer since all three values changed after the transformation, but that answer if wrong.

•If you shift the original data (C1) as follows: C3=C1+5 how would you answer the same question?

I chose "only the standard deviation" because it didn't change, but that answer is wrong.

3) Use your answers in 1) and 2), which of the three statistics you calculated satisfies that "the statistic of the transformed data is the same as the transformed statistic of the original data": [Hint: the transformed mean of the original data is the mean of the original data/5] O a) None of them O b) Only the mean O c) Only the median O d) Only the standard deviation O e) Only the mean and median O f) Only the mean and standard deviation O g) Only the median and standard deviation O h) All of them
