Question

A dot plot with an axis marked from 0 to 10 at increments of 1 is shown. Plot shows 8 dots at 0, 7 dots at 1, 5 dots at 2, 4 dots at 3, 2 dots at 4, and 1 dot at 10.

A)
The mean is equal to the median and the data are symmetric.

B)
The peak is equal to the median and the data are skewed.

C)
The data are skewed and there is an outlier.

D)
The data are symmetric and there is an outlier.

Answer 1

The given information in the dot plot is,

i) An outlier is present at 10.

ii) The data's majority are concentrated at 0 to 4 interval.

iii) 10 is the only one, which is far away.

iv) We confirm that the data are skewed.

v) Because the most data is concentrated in one median's side.

Then the final answer will be,

C) The data are skewed and there is an outlier.

Therefore, option (C) is the answer.

Answer 2

• C) The data are skewed and there is an outlier.

Explanation:

Its clear from the dot plot that:

• There is an outlier at 10, since majority of data are concentrated at 0-4 interval with only one far away.
• The data are skewed, since most data concentrated to one side of the median.

So, the correct choice is C
