The tally chart shows the marks
that students in a class received in a mathematics test. Using the information from the
tally chart, complete the frequency table.
In this question, we are given a
tally chart for the marks of students in a mathematics test and asked to use this to
complete a frequency table. To do this, we can start by
recalling that the frequency in each column of the table is the number of people who
scored those marks. And we can find this using the
tally chart. We do this by recalling that each
line in a tally chart represents a frequency of one. So we see that in the first column
of the tally chart there are nine lines, so the frequency is nine. We can then add this into our
frequency table. The frequency of the first set is
nine.
We need to follow this process for
every column in the table. In the next column in the tally
chart, we see that there are 14 lines. So, the frequency of the second
column in our frequency table is 14. Continuing this process, we find a
frequency of 12 in the next set, a frequency of 16 in the set starting at 20, and a
frequency of six in the final set. Writing these frequencies in order,
we have found that the frequencies are nine, 14, 12, 16, and six.
