Finding the Mean, Median and Mode
Objectives: a. . Find the mean, median, mode of a statistical data. b. Solve problems involving mean, median, mode. c. Describe the data using information from the mean, median, and mode. d. Appreciate the measures of central tendency in real life. Meanis commonly referred to as the average of all values. To compute for the mean, add all the scores and divide the sum by the number of scores. It is the easiest “average” to compute.The most frequent score/s in the given set of data is called the modeIt is also an “average” score. A data set may have two modes (and hence the data set is called bimodal). The medianis also an “average” score. It is themiddle score in the list after the scores are arranged in decreasing or increasing order. 1. The set of data shows a score of 35 students in their periodical test.

Motive Questions:
1. What score is typical to the group of students? Why?
2. What score frequently appears? 3. What score appears to be in the middle? How many students fall below this score? 2. The following sets of data show the height (in centimeters) of two groups of boys playing basketball at Maragondon town plaza. Group A: 135 136 140 150 134 129 126 Group B: 167 136 119 136 160 178 126 a. Compute for the mean b. What information can you get from these two values? The following sets of data show the weekly income (in peso) of ten households living in two different barangays in the town of Maragondon, Cavite. Brgy. Garita A: 150 1500 1700 1800 3000 2100 1700 1500 1750 1200 Brgy. Kaingin : 1000 1200 1200 1150 1800 1800 2000 1470 8000 a. Compute for the mean and median for each Barangay. b. What information can we get from these values? c. Why do you think the median is more appropriate than the mean?
