Question
When the data consists of 3, 4, 5, 4, 3, 4, 5, which statement is true?
✓

Answer

  1. Mean = mode
Solution:
The mean is equal to the sum of all the values in the data set divided by the number of values in the data set.
Mean of the given data is (3 + 3 + 4 + 4 + 4 + 5 + 5) ÷ 7 = 4.
The mode in a list of numbers refers to the integers that occur most number of times.
So the mode is also 4.
Hence mean = mode
