Exam 1: The Where, Why, and How of Data Collection

Nominal data is the highest level of data.

Assuming that you are planning to collect data using an experiment, it will be very important to establish an appropriate survey design.

The Polson Pole and Fence Company recently did a quality check on the length of fence posts. To do this, each of the 400 posts in inventory was numbered. Numbers from 1 to 400 were placed in a bowl. Twenty numbers were selected from the bowl without looking. These 20 poles were the ones selected for the study. This type of sampling is called:

A sampling plan that requires a person to interview 100 people as they exit a department store would most likely be:

A company is interested in determining which of several advertising layouts is most effective at generating additional sales. The data collection tool that would most likely be used in this situation is:

On a survey, the questions pertaining to the background of the respondent (age, gender, etc.) are referred to as demographic questions.

The human resources department at a major high tech company recently conducted an employee satisfaction survey of 100 of its 3,000 employees. Data were collected on such variables as age, gender, marital status, current salary, level of overall satisfaction on a scale from 1 to 5, number of years with the company, and job title. Which of the variables would be considered to be qualitative data?

An open-end question requires respondents to choose from a short list of choices

When a marketing manager surveys a few of the customers for the purpose of drawing a conclusion about the entire list of customers, she is applying:

Recently, an analyst in a company's marketing department surveyed customers regarding how often they buy a particular product. One customer indicated that she purchased the product 17 times in the last six months, but the analyst recorded the response as 71 times. This is an example of observer bias.

In this course, the term business statistics refers to the set of tools and techniques that are used to convert information into meaningful data.

A retail store is interested in determining what its customers are looking for specifically when they go to the store. To collect the necessary data, interviewers stand near the store's entrance and survey every 10th customer. This type of sampling is called:

When a survey is done you can always assume that non-respondents would have answered the same way as those who did respond.

Discuss the two major types of descriptive statistics.

Selection bias occurs when the respondent decides which of the questions on the survey to answer.

A marketing researcher decides to perform in-depth interviews for ten individuals chosen from a group of twenty five consumers who taste tasted some new food products. In conducting a personal interview, what problem can result if the interviewer is arbitrarily decides who will be interviewed?

Simple random sampling involves selecting members of the population in such a way that all members are equally likely to be chosen.

Cross-sectional data is a set of data values observed at successive points in time.

Another term used for statistical sampling is:

Population parameters are descriptive numerical measures, such as an average, that describe the entire population.
