- 5. a. Define frequency distribution table; b. Organize the data collected using frequency distribution table; c.Construct a frequency distribution table given a set of data.
- 8. FREQUENCY DISTRIBUTION FREQUENCY DISTRIBUTION refers to the table that shows an item and its frequency. It is developed by counting or tallying how often each data value occurs.
- 9. Ungrouped data is data given as individual data points. Grouped data are framed by amassing singular perceptions of a variable into gatherings. Data as Ungrouped or Grouped.

- 19. Step 1: Solve for RANGE Subtract the lowest value from the highest value. Range = highest value – lowest value
- 20. Step 2: Set the desired number of classes Decide on the number of class interval desired. (usually 5 - 15). Step 3: Solve for the class width or class size i Divide the range by the desired number of class interval to determine the size of the class interval.
- 21. Step 4: Make the first class interval. Include the smallest value of the data. (Ex. 25-28) Step 5. Identify the class limits (apparent limits) Class limit is the highest and lowest values describing a class. (Example: The class intervals are 19 – 23, 24 – 28, 29 – 33...
- 22. Step 6. Determine the frequency of each class interval by counting the mark tally Class Interval Class Boundaries Tally Frequency Class Mark 45-48 41-44 37-40 33-36 29-32 25-28
- 23. Step 6. Determine the frequency of each class interval by counting the mark tally
- 24. Step 7. Distribute data in classes. The column for tally is optional. Class Interval Class Boundaries Tally Frequency Class Mark 45-48 III 3 41-44 IIII-II 7 37-40 IIII-IIII 10 33-36 IIII-I 6 29-32 IIII-III 8 25-28 IIII-I 6
- 25. To find CLASS BOUNDARY, add 0.5 to the upper class limit and subtract 0.5 to the lower class limit. The CLASS MARK is the midpoint of the class. It can be found by getting the average of the class limits. For example, the class mark for 45-48 can be solved by 45+48 2 = 93 2 = 46.5
