The table shows the number of days each student has been absent. Use the data to complete the frequency table.
As there are four rows and 10 columns, we know that there’re 40 students altogether as four multiplied by 10 is equal to 40. These students were either absent for zero, one, two, three, four, five, or six days. There are four zeros in the table. Therefore, four students were absent for no days. There’re seven ones in the table. This means that seven students were absent for one day.
Next, we look for the twos. There are five of these. Therefore, five students were absent for two days each. There are also five threes. So five students were also absent for three days.
Once again, there were five fours. So there were five students absent for four days. There’re four fives in our table. So four students were absent for five days each. Finally, there’re 10 sixes. Therefore, 10 students were absent for six days.
The missing numbers in the table were four, seven, five, five, five, four, and 10, respectively. As a check, it is worth adding these seven numbers to make sure they add up to 40 students. Adding four, seven, five, five, five, four, and 10 does indeed give us 40. This suggests that the numbers in our table are likely to be correct.
