Find the mode of the values, thirteen, twenty, three, three, three, twenty, twenty, eleven, three, thirteen, and twelve.
00:00:16.080 --> 00:00:18.360
Well the mode means the most frequently occurring.
00:00:18.800 --> 00:00:24.520
So we’re looking for which number occurs most often in that list.
00:00:25.920 --> 00:00:29.120
So what we need is a nice methodical way of working this out.
00:00:29.800 --> 00:00:32.000
So let’s start off with the number thirteen.
00:00:33.120 --> 00:00:36.000
That occurs once, and then once over here.
00:00:36.960 --> 00:00:40.240
So thirteen occurs twice.
00:00:41.520 --> 00:00:48.120
Now the number twenty, once, twice, three times.
00:00:49.280 --> 00:00:56.360
Now the number three, once, twice, three, four times.
00:00:57.400 --> 00:01:00.680
Eleven just occurs once.
00:01:01.480 --> 00:01:05.440
And twelve also just occurs once.
00:01:06.960 --> 00:01:16.720
So the mode, the number which appears with the highest frequency, or appears in that list more times than any other number, is this one here.
00:01:17.240 --> 00:01:25.840
The frequency of four, three appears four times, which is more than any other individual number in the list.
00:01:26.760 --> 00:01:30.720
So the answer is: The mode is three.
00:01:32.160 --> 00:01:41.400
Now a common mistake is to use the frequency of the most frequently occurring data value, so putting the answer four.
00:01:42.000 --> 00:01:43.440
That is definitely wrong.
00:01:44.680 --> 00:01:51.680
So remember, the mode is the data value that occurs the most often in the data set.
