Answer:
The mean of the tree heights at Yard Works is less than the mean of the tree heights at The Grow Station.
The range of the tree heights at Yard Works is greater than the range of the tree heights at The Grow Station.
The mean absolute deviation of the tree heights at Yard Works is equal to the mean absolute deviation of the tree heights at The Grow Station
The mean of the tree heights at Yard Works is less than that of The Grow Station.
The range of the tree heights at Yard Works is greater than that of The Grow Station.
The mean absolute deviation of Yard Works and The grow station are equal.
Mean is the average of a set of numbers. It is determined by adding the numbers together and dividing it by the total number
Mean = sum of the numbers / total number
Yard Works: (7+ 9 + 7 + 12 + 5) / 5 = 8
The Grow Station: (9+ 11 + 6 + 12 + 7)/ 5 = 9
Range is the difference between the highest and lowest values of a set of observations
Range = highest value - lowest value
Yard Works: 12 - 5 = 7
The Grow Station: 12 - 6 = 6
Mean absolute deviation for The Grow Station: |(9 - 9) + (11 - 9) + (6 - 9) + (12 - 9) + (7 - 9)| / 5 = 2
Mean absolute deviation for Yard Works: |(7 - 8) + (9 - 8) + (7 - 8) + (12 - 8) + (5 - 8)| / 5 = 2
Median can be described as the number that occurs in the middle of a set of numbers that are arranged either in ascending or descending order
Median of Yard works : 5, 7, 7, 9, 12 = 7
Median of The Grow Station: 6, 7, 9, 11, 12 = 9
