All right, so we're looking at some final exam grades for a stats course, and they're listed on the left.
00:08
And i sorted them from the smallest to the largest to help the count, help the counting of the stem and leaf plot.
00:17
So here's the stem, the 10s digit, leafs, the units digit, and break them apart like that.
00:28
Done.
00:29
There you go.
00:30
Calculate the relative frequencies.
00:36
So i did that right here.
00:38
The score 10 to 20, there was one of them.
00:44
So you take that value, did the count, right? use the stem and leaf plot to count.
00:48
Took that count divided by 42, because there were 42 total scores.
00:55
And then we want to make a relative frequency histogram.
01:01
So i did the histogram itself with the counts and then the relative frequency.
01:07
But google sheets doesn't, it doesn't allow you to make these bars.
01:12
This is a bar chart...
