Answer :
- Directions: Solve for the mean, median and mode of the following ungrouped data: 5, 8, 9, 11, 8
MEAN
• You can find the mean, or average, of a data set in two simple steps:
- Find the sum of the values by adding them all up.
- Divide the sum by the number of values in the data set.
GIVEN : 5 , 8, 9, 11 and 8
- 5 + 8 + 9 + 11 + 8 ( Add them up l
- 41 ( The sum )
- 41 ÷ 5 ( Divide the sum by the number of values in the set.
- 8.5 ( The mean )
• Hence the mean of the values in the set is 8.5
MEDIAN
• The median is the central number of a data set. Arrange data points from smallest to largest and locate the central number. This is the median.
GIVEN : 5, 8, 9, 11, 8
- 5, 8, 8, 9, 11 - Arrange the numbers in increasing
- 8 - The median
The median is located in the center of the set in arranged.
• Hence the median of the values in the set is 8
MODE
•The mode of a data set is the number that occurs most frequently in the set. To easily find the mode, put the numbers in order from least to greatest and count how many times each number occurs. The number that occurs the most is the mode.
GIVEN : 5, 8, 9, 11, 8
- 5, 8, 8, 9, 11 - Arrange the numbers in increasing
- Number 8 occurs the most in the set
• Hence, the Mode of the values in the set is 8
ANSWER :
MEAN = 8.5 MEDIAN = 8 MODE = 8
