Using strategies explained in the video, find the mean, median, mode, and range of this data set:
{ 3, 4, 5, 6, 8, 8, 8 }
Which statement is true?
Question 1 options:
The mean is 6.
The median is 5.
The mode is 6.
The range is 8.
Mean: Add all the numbers together and divide by the total count.
Mean = (3 + 4 + 5 + 6 + 8 + 8 + 8) / 7 = 42 / 7 = 6
Median: The middle number when arranged in order. Since there are 7 numbers, the median is the 4th number.
Median = 6
Mode: The number that appears most frequently.
Mode = 8
Range: The difference between the highest and lowest numbers.
Range = 8 - 3 = 5
Therefore, the correct statement is: The mean is 6.
