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

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

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.

The following frequency table shows the number of strokes it took each golfer to complete Hole 3.

Number of strokes Number of golfers
111 000
222 444
333 141414
444 101010
555 444
666 222
What was the most frequent number of strokes?

I'm glad you asked! Based on the information you provided, the variable represented in the dotplot is quantitative and discrete. The number of strokes is a quantitative variable because it represents a numerical quantity. Additionally, it is discrete because it consists of distinct values (the number of strokes) rather than being a continuous range. So, the correct answer would be A.

The type of variable represented in the dotplot is quantitative and discrete.

To determine this, we need to understand the characteristics of the data.

Firstly, the variable being measured is "Number of Strokes", which represents a quantitative measurement.

Secondly, the data points on the dotplot are individual values indicating the number of golfers who took a particular number of strokes. In this case, the number of strokes is represented by whole numbers such as 62, 63, 64, etc., without any decimal or fractional values.

Therefore, the variable is quantitative (because it represents a numerical measurement) and discrete (because the values can only take on particular whole number values).

Hence, the correct answer is A) Quantitative and discrete.

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.

B or E?
