Hey there, welcome to numerade.
00:03
So we have 50 psychologists students here where they took a standardized test and basically their scores are summarized in the gfdt below.
00:14
So shown here, the scores in a frequency.
00:17
So we're trying to construct a relative frequency table here.
00:21
So what is the relative frequency for the third class? 220 to 239.
00:27
220 to 239.
00:29
So what we had to figure out first is our n value.
00:33
Our end value is basically our sample size, which is the sum of our frequency.
00:39
So we're going to take the sum of our frequency.
00:42
What we have here is to psychology students.
00:45
So it's already given to us.
00:47
If you add it, 16, 22, 40 and 10 to 50.
00:54
Yep...
