Hey there, welcome to numerade.
00:02
So we're looking at a number of texts in adults and teens and we're asking to construct a relative frequency distribution for adults.
00:11
So we first have to find the sample size.
00:14
The sample size here will be equivalent to the sum of the counts or you can say the sum of the frequencies.
00:21
Therefore, we're going to sum up all the numbers here.
00:24
You see 163 plus 971 plus 256 plus 255 plus 133 and plus 158, given us a grand total of 1 ,936.
00:46
For our sample size here, we're going to use our sample size as the denominator for our relative frequency because our relative frequency equals the frequency itself divided by the sample size.
01:11
But now we know the sample size equals 1 ,936.
01:18
So therefore that's going to be divided by.
01:23
So, for example, our first one here is none, so it would be 163.
01:29
So we're going to divide 163, divide 1936, giving us a relative frequency, rounded to three decimal places of 0 .084.
02:03
Okay.
02:04
Okay, so that was for none, right? so we have none.
02:13
So relative frequency for none is 0 .084...
