question

Shades of red paint in a home improvement store

answer

Shades of paint are descriptions and cannot be measured, so these are qualitative data.

question

Rankings of the most popular paint colors for the season

answer

Rankings are numeric but not measurements or counts, so these are qualitative data.

question

Amount of red primary dye necessary to make one gallon of each shade of red paint

answer

The amounts of dye needed are measured and therefore are quantitative data

question

Numbers of paint choices available at several stores

answer

The numbers of paint choices must be counted, so they are quantitative data as well.

question

Temperatures in Fahrenheit of cities in South Carolina

answer

Temperatures could be measured to any level of precision based on the thermometer used, so these are continuous data.

question

Numbers of houses in various neighborhoods in a city

answer

Numbers of houses are discrete data because houses are counted in whole numbers. A house under construction is still a house.

question

Numbers of elliptical machines in every YMCA in your state

answer

The numbers of elliptical machines are counts, so these are discrete data.

question

Heights of doors

answer

Heights are measurements and again, depending on the ruler, the heights could be measured to any level of precision, so they are continuous data.

question

Suppose all students in a statistics class were asked what pizza topping is their favorite. Explain why these data are at the nominal level of measurement.

answer

These data are nominal because the data simply describe or label the different toppings of the pizza.

question

Suppose instead that you wish to know the number of students whose favorite pizza topping is sausage. Explain why this data value is not at the nominal level of measurement.

answer

In the second scenario, the data value is a count of students who prefer sausage. This data value is quantitative, not qualitative, so it is not a label and would not be considered to be at the nominal level of measurement.

question

The seat numbers on your concert tickets, such as A23 and A24

answer

Seat numbers are ordinal because there is a meaningful order to the data, namely, the position in the theater.

question

The genres of the music performed at the 2013 Grammys

answer

Despite the fact that you may have your own personal preference for specific genres of music, there is no standard order. Therefore, music genres are nominal data.

question

The birth years of your classmates are collected. What level of measurement are these data?

answer

Birth years can be ordered. It is also meaningful to subtract years to determine the difference in age. However, the year 0 A.D. does not mean the beginning of time. Therefore, birth years are at the interval level of measurement.

question

Qualitative Data

answer

consists of labels or descriptions of traits

question

Quantitative Data

answer

consists of counts and mearsurements

question

Contnuous Data

answer

are quantitative data that can take on any value in a given interval and are usually measurements

question

Discreate Data

answer

are quantitative data that can take on ONLY particular values and are usually counts

question

Nominal level

answer

are qualitative data consisting of labels or names

question

Ordinal level

answer

are qualitative data that can be arranged in a meaningful order, but calculations such as addition or division do not make sense

question

Interval Level

answer

are quantitative data that can be arranged in a meaningful order, and differences between data entries are meaningful

question

Ratio Level

answer

quantitative data that can be ordered, differences between data entries are meaningful, and zero pt indicates the absence of something

question

Consider the ages in whole years of US presidents when they were inaugurated. What level of measurement are these data?

answer

The ages of US presidents are measurable, can be ordered, and an age of zero indicates the absence of life. Therefore, ages are at the ratio level of measurement. In contrast to Example 1.8, involving birth years, you can be twice as old as someone else.

question

Finishing times for runners in the Labor Day 10K race

answer

The amount of time it takes for each runner to run the race is quantitative since calculations performed on these data are meaningful. A finishing time is a measurement, therefore the data are continuous. Differences between finishing times are meaningful, and a time of zero represents the absence of racing. We could also say that Andrew finished the race in half of Peyton's time; thus, the data are at the ratio level of measurement

question

Colors contained in a box of crayons

answer

Colors are labels, so these data are qualitative. Qualitative data are neither discrete nor continuous. There are many ways to order colors, such as alphabetically or based on the color spectrum. However, when discussing colors of crayons, order is not the primary factor, as opposed to data such as rankings, in which order is important. Therefore, the data are at the nominal level of measurement.

question

Boiling points (on the Celsius scale) for various caramel candies

answer

Calculations can be performed on boiling points because they are measurements, making these data quantitative. Temperatures are measurements, so the data are continuous. For the Celsius scale, a temperature of zero degrees is simply a placeholder and does not indicate the absence of heat. Therefore, data from the Celsius scale are always at the interval level of measurement.

question

The top ten Spring Break destinations as ranked by MTV

answer

Since the rankings cannot be meaningfully added or subtracted, the data must be qualitative. Qualitative data are neither discrete nor continuous. The rankings are in a specific order, so the data are at the ordinal level of measurement.
