The line plot represents the number of hours that a group of people spent
exercising in a week. How many people were in the group?

Well in a line plot, the đ„-axis contains all the different categories. And in this
case, that represents the number of hours of exercise that they did, so either one hour or two
hours or three hours or four hours or five hours.

And the number of crosses that you see against each of those categories tells you
about the frequency, so how many people within the group said they did that number of hours. So
for example, one person said they did one hour, three people said they did two hoursâ exercise, four people said they did three hoursâ exercise, only one person said they did four hoursâ exercise, and two people said they did five hoursâ exercise.

So we can see from that that the most popular category was to do three hours;
four people did three hours; thatâs more than any other particular number of hours. And the least popular, well one and four, so fewer people did one than any other
category and fewer people did four hoursâ exercise than any other category.

Now the question says how many people were in the group? And to find out that answer, we need to add up all these numbers: the one
person who did one hours plus the three people who did two hoursâ exercise plus the four
people who did three hours plus the one who did four hours plus the two people who did five
hours.

And if I add up those numbers, I get eleven people.
So the answer is, there were eleven people in the group.
