How do you enter data as a frequency table?
Simple. Write data elements (separated by spaces or commas, etc.), then write f: and further write the frequency of each data item. Each element must have a defined frequency that counts numbers before and after the symbol f: must be equal. For example:1.1 2.5 3.99
f: 5 10 15
How to enter grouped data?
Grouped data are formed by aggregating individual data into groups so that a frequency distribution of these groups serves as a convenient means of summarizing or analyzing the data.| group | frequency |
| 10-20 | 5 |
| 20-30 | 10 |
| 30-40 | 15 |
10-20 20-30 30-40
f: 5 10 15
How to enter data as a cumulative frequency table?
Similar to a frequency table, but instead, f: write cf: in the second line. For example:10 20 30 40 50 60 70 80
cf: 5 13 20 32 60 80 90 100
The cumulative frequency is calculated by adding each frequency from a frequency distribution table to the sum of its predecessors. The last value will always equal the total for all observations since the calculator will have already added all frequencies to the previous total.
