Now data entry is complete.
Alternative entry procedure - Frequency table (using
a weight list)
In the previous example, scores of the mathematics and physics tests are sequentially
input into the lists L1 and L2, respectively. If the same data is duplicated, it is also
possible to separately input the data values and their quantities.
For example, consider the points of the chemistry test shown in the following table.
Student A
Chemistry 75
The table below shows the results after the above table is classified by points.
Points
Number of students
In the same manner as described previously, when inputting points to the list L3 and
number of students to the list L4, the list shown to the right is obtained.
At this time, the list L4 is called weight list (Freq.) of the
list L3. L3 and L4 are handled together as statistical data.
The weight list is used to draw the statistical graph or
calculate the statistical verification calculation described
later. If no weight lists exist, the specification of a list
name is unnecessary.
