00:00:01.510 --> 00:00:07.060
The graph represents the number of visitors to a restaurant on different days of the week.
00:00:08.290 --> 00:00:11.170
Which day had the fewest visitors?
00:00:12.880 --> 00:00:15.950
This bar graph shows six pieces of data.
00:00:16.520 --> 00:00:20.800
We can see that the đť‘Ą-axis is labelled with the title day.
00:00:21.560 --> 00:00:28.790
Each of the bars represents a different day of the week from Saturday through to Thursday.
00:00:29.520 --> 00:00:34.300
We can also see that the đť‘¦-axis is labelled number of visitors.
00:00:34.970 --> 00:00:41.030
This is because as the first sentence tells us, the graph represents the number of visitors to a restaurant.
00:00:41.820 --> 00:00:47.590
And if we look at the scale on the đť‘¦-axis, we can see each interval is worth 20.
00:00:48.100 --> 00:00:49.680
Thatâ€™s 20 visitors.
00:00:50.630 --> 00:00:54.770
The question asks us, which day had the fewest visitors?
00:00:56.130 --> 00:01:01.570
In other words, on which day did least people visit the restaurant?
00:01:02.850 --> 00:01:04.730
There are two ways to find this answer.
00:01:05.480 --> 00:01:19.220
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.
00:01:20.300 --> 00:01:23.520
But there is a quicker, more efficient way to find the answer.
00:01:24.150 --> 00:01:29.160
We know that the taller the bar on our bar graph, the more the visitors.
00:01:29.690 --> 00:01:34.500
And the opposite is true, the shorter the bar, the less the number of visitors.
00:01:35.350 --> 00:01:41.510
As though, if weâ€™re looking for the day that has the fewest visitors, we need to look for the bar thatâ€™s the shortest.
00:01:42.390 --> 00:01:44.510
Monday and Thursday look pretty short.
00:01:45.100 --> 00:01:46.090
Letâ€™s compare them.
00:01:46.820 --> 00:01:54.780
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.
00:01:55.250 --> 00:02:00.050
In fact, the bar that represents Monday only gets up as far as the first interval on the scale.
00:02:00.670 --> 00:02:05.980
There were 20 visitors on Monday, and no other day had as few visitors as this.
00:02:06.610 --> 00:02:12.200
To look for the day with the fewest visitors, we needed to look for the bar that was shortest.
00:02:12.580 --> 00:02:16.560
The shortest bar on our graph is the one that represents Monday.
00:02:17.210 --> 00:02:23.340
And so, we can say the day where the fewest number of visitors came to the restaurant was Monday.
