A student recorded her scores on weekly math quizzes that were marked out of a possible 10 points. Her scores were as follows: 8, 5, 8, 5, 7,6, 7, 7, 5, 7, 5, 5, 6, 6, 9, 8, 9, 7, 9, 9, 6, 8, 6, 6, 7. Find out mode.
Answers
Answer:
Mode = most occurring number = 7 and 6
Step-by-step explanation:
Both 7 and 6 occurred 6 times each
Answer:
The given data is bimodal data with modes are 6 and 7
Step-by-step explanation:
Given,
The marks scored in weekly math quizzes are 8, 5, 8, 5, 7,6, 7, 7, 5, 7, 5, 5, 6, 6, 9, 8, 9, 7, 9, 9, 6, 8, 6, 6, 7.
To find,
The mode of the data
Recall the concept
Mode is the most frequently occurring value in a set of observations.
Solution:
In the set of observations 8, 5, 8, 5, 7,6, 7, 7, 5, 7, 5, 5, 6, 6, 9, 8, 9, 7, 9, 9, 6, 8, 6, 6, 7.
There are 25 observations. In these 25 observations
5 occurs 5 times
6 occurs 6 times
7 occurs 6 times
8 occurs 4 times
9 occurs 4 times
Here both observation 6 and 7 occurs the maximum number of times.
Hence the given data is bimodal data with modes are 6 and 7
