Question 1

Which measure of central tendency is appropriate for interval scales?

Accepted Answer

The mean is the most appropriate measure of central tendency for interval scales as it takes into account the numerical values of the scale, which are evenly spaced. The mode and median can also be used, but they are less precise and may not accurately represent the typical value of the data. Range and dispersion are not measures of central tendency, but rather measures of variability.

Question 2

Differences in respondent responses associated with where the interview took place,such as at the mall,in a home,or over the telephone are errors originating from the _____ associated with the study.

Accepted Answer

Situational factors such as the location of the interview can introduce errors in the data collected. These factors can influence respondent behavior and responses, leading to inconsistencies in the results. The other options (respondent, interviewer, instrument, sample) refer to other potential sources of error, but do not directly relate to differences in response based on situational factors.

Question 3

What is the median for the business research exam scores?

Accepted Answer

The answer of What is the median for the business...

Question 4

Calendar time is expressed on a(n)_____ scale while minutes,hours,and days are expressed on a(n)_____ scale.

Accepted Answer

Calendar time is expressed on an interval scale because the units of measurement (months, days) are equally spaced and ordered. Minutes, hours, and days are also expressed on an interval scale because time measurements are continuous and ordered, but there is no true zero point.

Question 5

The appropriate measure of central tendency for an ordinal scale is the _____.

Accepted Answer

The appropriate measure of central tendency for an ordinal scale is the median. This is because ordinal data is ranked in a specific order, but the intervals between values may not be equivalent. Therefore, using the mean (average) would not be appropriate as it assumes equal intervals between values. The mode is not a reliable measure of central tendency for ordinal data because there may be multiple values with the same frequency. The range and dispersion are measures of variability, not central tendency.

Question 6

A ratio scale contains _____.

Accepted Answer

A ratio scale contains the properties of classification, order, equal distance, and unique origin, which means that it has mutually exclusive and collectively exhaustive categories and the property of order, distance, and a unique starting point. This allows for meaningful comparisons using ratios and mathematical operations such as multiplication and division.

Question 7

In a survey of football fans,each respondent is asked to indicate whether they have ever attended an NFL game.This question can be categorized as a(n)_____ scale.

Accepted Answer

The question only asks for a yes or no response and does not involve any rankings or values, hence it falls under the nominal scale.

Question 8

The _____ is the midpoint of a distribution.

Accepted Answer

The midpoint of a distribution is also known as the median. It is the value that separates the lower half of the distribution from the upper half. The mode is the most frequently occurring value, the mean is the average of all the values, the range is the difference between the maximum and minimum values, and dispersion refers to the amount of variability or spread in the distribution.

Question 9

The population of a city is an example of _____ data.

Accepted Answer

The population of a city is an example of ratio data because it has a natural zero point (indicating no inhabitants) and the differences between values can be meaningfully interpreted. Ratio data allows for a full range of quantitative comparisons, including addition, subtraction, multiplication, and division.

Question 10

When the groups are mutually exclusive and collectively exhaustive,nominal scales must be limited to _____ groups.

Accepted Answer

Nominal scales, which categorize data without implying any order, are not inherently limited in the number of groups they can have, as long as the groups are mutually exclusive (no overlap) and collectively exhaustive (covering all possibilities).

Question 11

The effects of fatigue,boredom,and social class on the measurement of an object are all errors originating from the _____.

Accepted Answer

These errors are associated with the respondent because they relate to the individual's personal state (fatigue, boredom) and social background (social class), which can influence their responses or how they interact with the measurement process.

Question 12

What is the mode for the business research exam scores?

Accepted Answer

The mode is the most common score in a data set. Looking at the options given, the score 78 appears twice, while all other options appear only once. Therefore, the mode is 78.

Question 13

A nominal scale contains _____.

Accepted Answer

Nominal scales only have mutually exclusive and collectively exhaustive categories, but do not have the properties of order, distance, and origin.

Question 14

When analyzing nominal data,which measure of central tendency is appropriate?

Accepted Answer

The mode is the most appropriate measure of central tendency for nominal data because it identifies the most frequently occurring category or value within the dataset. Nominal data represent categories that cannot be logically ordered or quantified in terms of magnitude, making measures like mean and median, which rely on numerical values and their order, unsuitable.

Question 15

Random error in measurement is the error that occurs _____.

Accepted Answer

Random error is an unpredictable error that occurs erratically and cannot be detected or eliminated. It is caused due to various reasons such as human error, environmental factors, etc.

Question 16

The New York Times Dining Section rates the restaurants it reviews using a system such that one star means good,two stars means very good,three stars means excellent,and four stars means extraordinary.This is a type of _____ scale.

Accepted Answer

The rating system used by The New York Times Dining Section is an example of an ordinal scale. This is because the categories (one star, two stars, three stars, four stars) are ordered and ranked, but there is no inherent numerical value assigned to each category.

Question 17

What is the arithmetic mean for the business research exam scores?

Accepted Answer

The arithmetic mean is calculated by summing all the exam scores and dividing by the number of scores. The correct mean is 74.4.

Question 18

An interval scale contains _____.

Accepted Answer

An interval scale has the properties of order, classification, and equal distance between points but no unique origin, as the zero point is arbitrarily assigned.

Question 19

_____ describes how scores cluster or scatter in a distribution.

Accepted Answer

Dispersion measures the extent to which a distribution is spread out or clustered together. It includes measures such as variance, standard deviation, and interquartile range. Options A, B, C, and E do not directly relate to the spread or clustering of scores in a distribution.

Question 20

An ordinal scale contains _____.

Accepted Answer

An ordinal scale categorizes data into mutually exclusive and collectively exhaustive categories while also possessing the property of order. However, it does not have the properties of distance or unique origin.
