A college basketball player scored the following points in the 37 games he played his senior year:
Stem-and-leaf of points n = 37
Leaf Unit = 1.0
1|33
1|66
2|1233444
2|5555666789
3|0222233444
3|89
4|23
4|7
5|2
The first quartile of his point totals is ____________ points
1|3366
2|12334445555666789
3|022223344489
4|237
5|2
The first quartile, if your plot was to be divided equally into 4 quarters, would be from the first point around the 9th point. So for example, if you're staring from the top, you'd add up the points from 1.3-2.4 (The first one)

To find the first quartile of the basketball player's point totals, we need to understand the stem-and-leaf plot. The stem-and-leaf plot shows the stems (tens digit) and leaves (ones digit) of each data point.
Looking at the stem-and-leaf plot given, we see that the stems range from 1 to 5, representing the tens digit of the data points. The leaves represent the ones digit.
To find the first quartile, we need to divide the data into four equal parts. Since we have 37 data points, the first quartile falls at the 25th percentile.
Counting the data points from left to right, we see that the 25th data point lands in the stem 2 with the leaf 5. This means that the first quartile of the player's point totals is 25 points.
