1. PRESENTATION OF DATA

2. There are three ways of presenting data: Tabular Method Graphical Method Textual Method

3. Learning Outcomes: At the end of this module, you should be able to: Describe the tabular method of presenting data Construct a frequency distribution table for group and ungrouped data Construct a stem-and-leaf plot Write the correct syntax of the countif command in Excel and use it to find the frequency of a particular data set

4. TABULAR PRESENTATION It is a systematic and logical arrangement of data in the form of Rows and Columns with respect to the characteristics of data. It is an orderly arrangement which is compact and self-explanatory.

5. Parts of a Table

10. Frequency Distribution for Grouped Data Grouped data is data that has been organized into groups from the raw data.
