The graph represents the number of visitors to a restaurant on different days of the week. Which day had the fewest visitors?

This bar graph shows six pieces of data. We can see that the 𝑥-axis is labelled with the title day. Each of the bars represents a different day of the week from Saturday through to Thursday. We can also see that the 𝑦-axis is labelled number of visitors. This is because as the first sentence tells us, the graph represents the number of visitors to a restaurant. And if we look at the scale on the 𝑦-axis, we can see each interval is worth 20. That’s 20 visitors.

The question asks us, which day had the fewest visitors? In other words, on which day did least people visit the restaurant? There are two ways to find this answer. Firstly, we could go through all the days of the week, read the graph to see the number of visitors that attended on each day, and then just look for the smallest number because the smallest number will be the fewest visitors.

But there is a quicker, more efficient way to find the answer. We know that the taller the bar on our bar graph, the more the visitors. And the opposite is true, the shorter the bar, the less the number of visitors. As though, if we’re looking for the day that has the fewest visitors, we need to look for the bar that’s the shortest. Monday and Thursday look pretty short. Let’s compare them. If we draw a line across from the top of the bar that represents Monday, we can see that this is less than the bar that represents Thursday.

In fact, the bar that represents Monday only gets up as far as the first interval on the scale. There were 20 visitors on Monday, and no other day had as few visitors as this. To look for the day with the fewest visitors, we needed to look for the bar that was shortest. The shortest bar on our graph is the one that represents Monday. And so, we can say the day where the fewest number of visitors came to the restaurant was Monday.
