The following dotplot shows the number of strokes taken by 20 professional golfers competing at an 18-hole golf course.

Question

B? or E? I'm not sure if it would be considered categorical or continuous? It is definitely quantitive.
The figure presents a dotplot titled Number of Strokes, and the numbers 62 through 70 are indicated, in increments of 1. The dotplot contains 20 data points. The data are as follows. 62 strokes, 0 golfers. 63 strokes, 0 golfers. 64 strokes, 2 golfers. 65 strokes, 4 golfers. 66 strokes, 2 golfers. 67 strokes, 6 golfers. 68 strokes, 3 golfers. 69 strokes, 3 golfers. 70 strokes, 0 golfers.
Which of the following best describes the type of variable represented in the dotplot?
A??

Quantitative and discrete
A

Quantitative and continuous
B

Categorical and discrete
C

Categorical and continuous
D

Quantitative and categorical
E

Answer 1

B or E?

Answer 2

A.
Because the data is quantitative (number of strokes) and also because this data is discrete. You cannot have half a golf swing, but only a full golf swing, making this data discrete and NOT continuous.

Answer 3

Assume that the Weight of the students in your sample enrolled at NSU have an
approximately Normal distribution. Find the probability that the mean Weight of your
sample selected from the university is (Quantitative variable)
mean weight 67.41 & standard daviation 14.41.
A. Within 2 standard deviations from the mean.
B. More than 1 standard deviation from the mean.
