Introduction:
We will discuss the definitions of the mean, median, and mode.
Methods/Procedures:
- Students will count and graph the number of pieces of candy in their packs by color. Each student will graph his/her results.
- Use the above data to figure the mean, the average number of pieces of candy of each color. For example, if the data indicates 1 red candy, 2 green candies, 3 orange candies, 7 yellow candies, and 7 purple candies, the mean, or average number of pieces of each color is 4. [ (1 + 2 + 3 + 7 + 7) / 5 = 4 ]
- Use the data to calculate the median, or middle number. [3]
- Use the data to calculate the mode, or the number that occurs most frequently. [7]
- The students will record their data on a worksheet and graph their findings.
- We will compile all data and find a class-wide mean, median, and mode.
Accommodations/Adaptations:
I will assist any students with special needs in the counting of their candy.
Assessment/Evaluation:
They will turn in their worksheets and graphs for grading.
