If a constant is added to each value in a given data set to produce a new data set, which one of the following describes how the
Ostrovityanka [42]

Answer:  C. Equal to

Step-by-step explanation:

The standard deviation is written as:

Sx = √( ∑(xₙ - x)^2/(n-1))

Where xₙ are the values of the data set, n is the number of data points and x is the mean of the data set.

Now, if we add a constant c to all the terms in our data set we will have:

(i will use the ' to denote the transformed data)

xₙ' are now xₙ + c.

And the new mean will be:

x' = ( (x₁ + c) + (x₂ + c) + .... + (xₙ + c))/n = (c*n + (x₁ + x₂ + ..))/n = c + (x₁ + x₂ +...)/n

x' = c + x

Then the new standard deviation will be:

Sx' =√( ∑(xₙ' - x')^2/(n-1))

Sx' = √( ∑((xₙ+c) - (x +c))^2/(n-1)) = √( ∑(xₙ - x)^2/(n-1)) = Sx

So the standard deviation does not change.

The correct option is C.
