Question 1

Determine which of the following describes qualitative data.
i). the volume of a shipping container, in gallons
ii). the name of the material from which the container is made
iii). the shape of the container
A) i, ii, and iii
B) $\mathrm { i }$ and iii only
C) ii and iii only
D) $\mathrm { i }$ and ii only

Accepted Answer

Qualitative data refers to non-numeric information that describes characteristics or qualities. The name of the material (ii) and the shape of the container (iii) are examples of qualitative data, as they describe attributes rather than quantities. The volume of a shipping container (i), expressed in gallons, is quantitative data because it provides a numeric measurement.

Question 2

What level of measurement classifies data into mutually exclusive categories in which no order or ranking can be imposed on the data?
A) ordinal
B) nominal
C) ratio
D) interval

Accepted Answer

Nominal level of measurement classifies data into categories that are mutually exclusive without any inherent order or ranking among the categories.

Question 3

Quantitative data can be further classified as continuous or nonsequential.

Accepted Answer

Quantitative data can be further classified as continuous or discrete, not nonsequential. Continuous data can take any value within a range, while discrete data can only take specific values.

ii). the mass of a chemical sample
iii). the color of a chemical sample
A) $i$ and ii only
B) $i$ only
C) i, ii, and iii
D) ii only

Accepted Answer

Quantitative data refers to data that can be measured and written down with numbers. Among the options, only the mass of a chemical sample (ii) fits this description, as it can be quantitatively measured in units such as grams or kilograms.

Question 10

Determine which of the following describes quantitative data.

A) $i$ and ii only
B) $\mathrm { i }$ only
C) iii only
D) i, ii, and iii

Accepted Answer

Quantitative data refers to data that can be measured or counted. All three options (i, ii, iii) describe measurable quantities: length in feet, speed in meters per second, and the count of blue objects, making them examples of quantitative data.

Question 11

The amount of time needed to run the Boston marathon is an example of which type of variable?
A) continuous
B) temporal

Question 13

Determine which of the following describes ordinal data.
i. My best friends are Georgia, Amithaba, and Raphael.
ii. My favorite numbers are 2,7 and 13 .
A) i only
B) both $\mathrm { i }$ and ii
C) ii only
D) neither i nor ii

Accepted Answer

Ordinal data refers to data that can be ordered or ranked but does not necessarily have a consistent difference between rankings. Both examples given, names of friends and favorite numbers, do not fit this definition. Names cannot be ranked in a meaningful way that reflects ordinal data, and favorite numbers, while numeric, are not presented in a context that suggests a ranking or order with meaningful intervals.

Question 14

Determine which of the following describes ordinal data.
i. In the horse race, Betty's Girl won, Mr. Ed placed, and Wabash showed.
ii. In the horse race, I bet on Betty's Girl to win, Mr. Ed to place, and Wabash to show.
A) neither i nor ii
B) both $i$ and ii
C) i only
D) ii only

Accepted Answer

The answer of Determine which of the following describes ordinal...

Question 15

Determine which of the following describes nominal data.
i. My favorite days of the week are Friday, Saturday, and Tuesday.
ii. My favorite day of the week is Friday, my second-favorite is Saturday, and third-favorite is Tuesday.
A) both $\mathrm { i }$ and ii
B) neither i nor ii
C) ii only
D) i only

Accepted Answer

Nominal data categorizes without a natural order or ranking. Statement i lists days without implying any order, fitting the definition of nominal data. Statement ii introduces a ranking, making it ordinal data, not nominal.

Question 16

The variable of height is an example of a quantitative variable.

Accepted Answer

Height is measured on a numerical scale, making it a quantitative variable because it quantifies an amount.

Question 17

Classifying the fruit in a basket as apple, orange, or banana, is an example of the ___________ level of measurement?
A) interval
B) ratio
C) ordinal
D) nominal

Accepted Answer

Classifying fruits into categories like apple, orange, or banana is an example of nominal level measurement because it involves categorizing or naming attributes without any quantitative value or order.

Question 18

Determine which of the following describes nominal data.
i. Michaelangelo's sells small, medium, large, and jumbo pizzas.
ii. Michaelangelo's most-requested toppings are pepperoni, black olives, and mushrooms.
A) both $\mathrm { i }$ and ii
B) neither $\mathrm { i }$ nor ii
C) i only
D) ii only

Accepted Answer

Nominal data refers to data that can be categorized but not ranked or ordered. Both examples (i) and ii) describe categories (sizes of pizzas and types of toppings) without any inherent order, making them nominal data.

Question 19

What level of measurement allows for the ranking of data, a precise difference between units of measure, and also includes a true zero?
A) nominal
B) ratio
C) ordinal
D) interval

Accepted Answer

Ratio level of measurement allows for the ranking of data, precise differences between units of measure, and includes a true zero, enabling calculations of ratios.

Question 20

Determine which of the following describes qualitative data.
i). the make of the car with license plate number VNS-862
ii). the license plate number VNS-862
iii). the number of vehicles whose license plate number begins with "VNS"
A) iii only
B) $i$ and ii only
C) neither i, nor ii, nor iii
D) $i$ only

Accepted Answer

Qualitative data describes non-numeric characteristics or categories. The make of the car and the license plate number are both non-numeric and categorical, thus qualitative.
