The table shows the marks that 32 students received in their mathematics test. Using this data, complete the frequency table.

We wanna take this huge list of scores and turn them into more manageable frequency table. To do this, we’ll sort each of these scores into the category that they belong in, starting with this 31.

31 falls between 30 and 34, so we can make a tally mark in this category for the score of 31; then we’ll cross 31 off the table. Our next value 32 also belongs in a category from 30 to 34. 41 falls between 40 and 44; we place our tally mark and then cross out 41. Next step, 27 falls between 25 and 29. 29 also falls between 25 and 29. And we are going to continue this process for each one of these numbers.

Once we’ve sorted each of the 32 scores, we can total our frequencies. There were a total of six scores ranging from 25 to 29, there were a total of seven scores ranging from 30 to 34, there were a total of six scores ranging from 35 to 39, there were seven scores in the range 40 to 44, there were a total of four scores in the Range 45 to 49, and finally there were two scores in the range 50 to 54. And this would be what a completed frequency table looks like for these 32 scores.
