Frequency Tables
Frequency Tables
Objective: To construct frequency tables.
Frequency Tables
At the end of this lesson you should be able to answer the following question.
Can you determine mean, median, or mode from a frequency table?
Frequency Tables
A frequency table is a graphical display showing how often a particular event occurred.
Frequency Tables
A frequency table is a graphical display showing how often a particular event occurred.
The intervals allow you to see the frequency distribution of the data or how many pieces of data are in each interval.
Frequency TablesThe list below shows a set of test scores. Make a
frequency table to represent the data.
How to Construct a Frequency Table. Step 1 – Create a three column table. The
1st column should be titled with the specific variable, the 2nd column – “tally”, and 3rd “frequency”
