A ________ indicates how far an individual raw score falls from the mean of a distribution; the ________ indicates how the score
I am Lyosha [343]

Answer:

A <u>z-score</u> indicates how far an individual raw score falls from the mean of a distribution; the <u>standard deviation</u> indicates how the scores in general scatter around the mean.

Step-by-step explanation:

We have been given an incomplete statement. We are supposed to complete the given statement.

We know that z-score of a data set indicates that a sample score or raw score is how many standard deviation away from the mean. Z-score indicates the distance of a raw score is above or below mean in units.

Therefore, the correct word for 1st blank would be "z-score".

We also know that standard deviation represents the variation of a data set. It tells that data points of a data set are how much close or away from mean of the data set.

Therefore, the correct word for 2nd blank would be "standard deviation".
