Question

x | f
5 | 2
4 | 4
3 | 1
2 | 3
how would you figure out how many participants there are based on the picture above?
count all the values in the x column and f column
count all the values in the f column only
number of participants cannot be determined
count all the values in the x column only

Explanation:

In a frequency table, the column labeled "f" (frequency) represents how many times each value of "X" occurs. To find the total number of participants, we need to sum the frequencies (the values in the "f" column) because each frequency tells us how many participants have that particular "X" value. Counting values in the "X" column would just give the number of different "X" values, not the total participants. And we can determine the number of participants by summing the frequencies. So we count (sum) all the values in the f column only.

Answer:

Count all the values in the f column only
