The frequency table represents the data set:
1, 1, 1, 2, 2, 2, 2, 4, 4.
The median is 2 because 4 data points appear before and after the center 2.

Thousands of people in the United States were surveyed about their grandparents. This frequency table shows their answer to the question "how many of your grandparents were born outside of the US?
Of the people who had at least one grandparent born outisde of the US, what percent had exactly 3 non-US born grandparents?

Tap to reveal answer
Adding up the total number of grandparents that were born outside the U.S. is our first step in solving this problem.
There are
people who said they had at least 1 grandparent born outside of the US. Of those, only 976 had exactly 3.
So
or

No - normally distributed data has a low frequency of responses at the high and low ends. Also, the majority of the data is in the middle.
In this data set, the majority of people said "0," and the fewest people said "3" which is near the middle of the data. If this data was normally distributed we would have a higher frequency between 1 and 3 and much lower values for 0 and 4.

Count the number of times each number appears in the data set.
The number 1 appears 4 times, so the first line is 
.
Then number 2 appears 7 times, so the next line is

Continuing in this fashion we see that the numbers 3, 4, and 5 appears 5 times and 6 appears once.
Therefore combining these together we get the following answer:

The correct frequency table represents the data set 3, 4, 5, 5, 6, 6, 8.
Since there are 7 data points our median will be the 4th spot which makes the value 5. It occures at the 4th spot because at that spot half the data points are below it while the other half are above it.
The center number of that data set is 5 as required.
