Determine the level of measurement (nominal, ordinal, interval, or ratio) for A patient's temperature (in degrees Fahrenheit) who has a fever.

As stated earlier in the text, temperature (measured in degrees Celsius or degrees Fahrenheit) is measured on the interval scale. In this case, 0 degrees Fahrenheit does not mean the absence of temperature which prevents us from calculating meaningful ratios.

Hair colors are an example of which type of data? Discrete, continuous, neither

Neither

Indicate the level of measurement for the data set described. Colors of cats owned by a sample of households Qualitative, Quantitative Discrete, continuous, neither nominal, ordinal, interval, ratio

Nominal

Classify the following data. Indicate whether the data is qualitative or quantitative, indicate whether the data is discrete, continuous, or neither, and indicate the level of measurement for the data. You toss a coin and record "head" as 1 and "tail" as 2. nominal, ordinal, interval, ratio

Qualitative Neither Nominal

State whether it is qualitative or quantitative. If the variable is quantitative, indicate whether it is discrete or continuous. Political party affiliation

Qualitative Examples of political party affiliation are Republican, Democrat, Independent, etc. These are qualitative measurements because they identify the party by name only and we are unable to perform any arithmetic operations or establish distances between parties. Thus, political party affiliation is a qualitative variable.

Classify the following data. Indicate whether the data is qualitative or quantitative, indicate whether the data is discrete, continuous, or neither, and indicate the level of measurement for the data. Your rating on a scale of 1 to 10 on the quality of a course. Qualitative, Quantitative Discrete, continuous, neither nominal, ordinal, interval, ratio

Qualitative Neither ordinal

level of measurement

Quality of data

Classify the following data. Indicate whether the data is qualitative or quantitative, indicate whether the data is discrete, continuous, or neither, and indicate the level of measurement for the data. The temperature in Fahrenheit of a U.S. city each day for a month. Qualitative, Quantitative Discrete, continuous, neither nominal, ordinal, interval, ratio

Quantitative continuous interval

Classify the following data. Indicate whether the data is qualitative or quantitative, indicate whether the data is discrete, continuous, or neither, and indicate the level of measurement for the data. The lifetimes of 100 five volt batteries is recorded. Qualitative, Quantitative Discrete, continuous, neither nominal, ordinal, interval, ratio

Quantitative continuous ratio

State whether it is qualitative or quantitative. If the variable is quantitative, indicate whether it is discrete or continuous. Number of online orders made per month

Quantitative, discrete The number of online orders is countable, starting at 0. Thus, this is a quantitative, discrete random variable.

Determine the level of measurement (nominal, ordinal, interval, or ratio) for A customer's response to a survey asking for their preferred brand of golf shoes: Footjoy, Nike, Adidas, Puma, or Ecco.

The customer's response will be only the name of the shoe brand. We cannot perform any arithmetic operations or ranking. Additionally, by the name only, one brand cannot be considered more (or better) than the other. Thus, shoe brand is measured on the nominal scale.

Determine the level of measurement (nominal, ordinal, interval, or ratio) for The number of gigabytes of data that a person uses on their mobile data plan.

The number of gigabytes used has a meaningful zero point and the ratio of two values for gigabyte usage is meaningful. That is, one who uses 16 gigabytes when compared to one who uses 4 gigabytes, a ratio of 4 can be calculated indicating that the customer using 16 gigabytes has used four times as much data as the customer using 4 gigabytes. Thus, the number of gigabytes used is measured on the ratio scale.

Determine the level of measurement (nominal, ordinal, interval, or ratio) for A student's response on a faculty evaluation: strongly disagree, disagree, somewhat disagree, somewhat agree, agree, strongly agree.

The student's response on the faculty evaluation is measured on the ordinal scale since we can have some order associated with the responses but cannot perform arithmetic operations.

Amounts of yearly rainfall in Miami over the last 55 years are an example of which type of data? discrete, continuous, neither

continuous

Discrete

data in which the observations are restricted to a set of values (1,2,3,4) that possesses gaps

Continuous

data that can take on any value within some interval

Nominal data

data that represents whether a variable possesses some characteristic

The numbers of people in each statistics class at your school are an example of which type of data? Discrete, neither, continuous

discrete

Interval

if the data can be ordered and the arithmetic difference is meaningful

Indicate the level of measurement for the data set described. Boiling points (in degrees Celsius) for various substances nominal, ordinal, interval, ratio

interval

Qualitative data

measurements that can change in kind, but not in degree often consist of labels or descriptions and do not have naturally occurring numerical values.

Quantitative data

measurements that change in magnitude from trial to trial such that some order or ranking can be applied can be measured using a naturally occurring numerical scale.

Indicate the level of measurement for the data set described. Ranks for members of the United States Army nominal, ordinal, interval, ratio

ordinal

A reviewer decides to interview viewers to see how they would rate a particular movie. The following table lists the responses from twenty-five viewers. What is the level of measurement for the data? Are the data qualitative or quantitative? ordinal, quantitative interval, qualitative nominal, quantitative ordinal, qualitative

ordinal, qualitative

Football jersey numbers are an example of which type of data? quantitative, parameter, statistic, qualitative

qualitative

State whether it is qualitative or quantitative. If the variable is quantitative, indicate whether it is discrete or continuous. Marital status

qualitative For marital status, examples could be single, married, or divorced. These are qualitative measurements since one classification cannot be considered to be more than another and we also cannot perform any arithmetic operations on this variable.

Amounts of yearly rainfall in Miami over the last 55 years are an example of which type of data? Qualitative, statistic, quantitative, parameter

quantitative

State whether it is qualitative or quantitative. If the variable is quantitative, indicate whether it is discrete or continuous. Amount of time spent on the computer

quantitative, continuous Examples of time spent on the computer could be any value from a few seconds to a large number of hours. Also, depending on the quality of the measurement, time could be recorded (or reported) in any number of significant digits. With that said, time spent on the computer is a quantitative, continuous random variable.

Indicate the level of measurement for the data set described. Number of athletes on the roster of each football team in the NCAA nominal, ordinal, interval, ratio

ratio

Ordinal data

represents categories that have some associated order

Ratio data

similar to interval data, except that they have a meaningful zero point and the ratio of two data points is meaningful
