3

Go through the set of numbers in the Question. For each number, see which of the group of numbers it belongs in. Cross it out and put a tally mark in the Tally column, in the row for that group of numbers.
  • The first number is 2. It belongs in the 1 - 5 group. Cross it out and put a tally mark in the Tally column in the 1 - 5 row. make_grouped_frequency_table_step_3_1
  • The second number is 10. Cross it out and put a tally mark in the Tally column in the 10 row. make_grouped_frequency_table_step_3_2
  • Continue until all numbers have been crossed out and had tally marks placed in the Tally column. make_grouped_frequency_table_step_3_3

4

For each row, count the tally marks. Write the number of tally marks in the Frequency column.
