Aresearcher asks participants to indicate how frequently they have used various illicit drugs using the following scale: 1 = never used; 2 = used 1 – 5 times; 3 = used 6 – 10 times; 4 = used more than ten times. this scale is best described as level.
a) nominal
b) ordinal
c) interval
d) ratio

The correct answer is C) interval. This scale is best described as interval level.

Step-by-step explanation:

Nominal, ordinal, interval, or ratio data are the four fundamental levels of measurement scales that are used to capture data.  

Nominal scales are used for labeling variables, without any quantitative value.

Ordinal the order of the values is what is significant, but the differences between each one is not really known.

Interval we know both, the order and the exact differences between the values

Ratio data they have the order, the exact value between units, and have an absolute zero

In this case, this scale is best described as interval level.

a. 3/4 ÷ 1/8 = 6

step-by-step explanation:

in the question, the number line represents 3/4 divided into 6 equal units. each arrow represents a unit and there are a total of six arrows.

the size of each unit is 1/8 as shown.

showing that 1/8 divides 3/4 into 6 divisions:

3/4 ÷ 1/8

= 3/4 x 8/1

= 3/1 x 8/4

= 3 x 2

= 6

hence, the number line represents six divisions given by 3/4 ÷ 1/8.

your answer   is c
