Question

The dot plot below shows the results of a recent patient survey at Brookwood Medical Center. 1. the data to answer the following questions. If necessary, round your answer to the nearest tenth
What is the mean score?

What is the median of the scores?

Answer 1

The mean of this dot graph is 3.4
The median of this dot graph is 3

Answer 2

Answer:

Median is 3

and mean is 3.3793

Step-by-step explanation:

the data set as we can see from the dot plot is

x:                    1    2    3    4   5

frequency:     2    4   9    9   5

mean of such set is equal to ratio of  product of x with their corresponding frequencies to sum of frequencies

  Mean= (1×2+2×4+3×9+4×9+5×5)/29

          = 98/29

          = 3.3793

median is the central tendency of the data sets

since, there are 29 observations so median is the 15th entry which is 3

Hence, median is 3

and mean is 3.3793
