(c) rita has recorded her golf score for each round shes played this year. which measure gives the score she shot the most often?
mean median mode

Explanation:

Step1: Understand measure definitions

Mean is the average, median is the middle - value, mode is the most frequent value.

Step2: Analyze (a)

The data set of house prices may have outliers. Median is less affected by outliers than the mean. So median is a better measure to summarize the data.

Step3: Analyze (b)

The car - price data set seems to be relatively symmetric without obvious outliers. Mean can be used to summarize the central tendency.

Step4: Analyze (c)

We want the score she shot the most often. By definition, that is the mode.

Answer:

(a) Median
(b) Mean
(c) Mode
