which data set has a variation, or mean absolute deviation, similar to the data set in the given dot plot?
which data set has a variation, or mean absolute deviation, similar to the data set in the given dot plot?
Answer
Explanation:
Step1: Recall mean - absolute - deviation concept
The mean absolute deviation measures the average distance between each data value and the mean. Visually, we can estimate it by looking at the spread of the data points in the dot - plot.
Step2: Analyze the given dot - plot
The given dot - plot has data points centered around 8 - 9 with a relatively small spread.
Step3: Analyze Option A
The data in Option A is centered around 8 but has a larger spread compared to the given dot - plot.
Step4: Analyze Option B
The data in Option B is centered around 55 but has a different spread pattern and is more spread out than the given dot - plot.
Step5: Analyze Option C
The data in Option C is centered around 8 - 9 and has a similar spread pattern and density of points as the given dot - plot.
Step6: Analyze Option D
There is no data shown for Option D in the image, but based on the previous analysis, Option C is a good match.
Answer:
C.
