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

Possibly the most frequently used nonstatistical sampling procedure is the simple random sample.

It is possible for the same survey questionnaire to yield both quantitative and qualitative data.

Typically,it is possible to include a larger number of questions in a phone survey than in a mail survey since it takes less time to complete the survey over the phone.

One of the major challenges for developing a good written questionnaire or telephone survey instrument is that:

When data are organized into levels,the highest data level is:

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

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

Which of the following types of questions provide the respondent with the greatest choice in responding to a question?

When the marketing manager for a large company surveys a portion of the total customers of his company,he is using a sample from the population.

Which one of the following is NOT statistical sampling?

Which of the following data collection methods is most likely to generate the largest nonresponse?

A common underpinning of all statistical sampling techniques is the concept of random selection.

When the park ranger at Yellowstone National Park reports the average length of time that visitors spend in the park,he is using:

If a population is very large,it may be better to select a sample from the population than to try to obtain a census in an effort to reduce measurement error.

One way to improve the response rate for a survey is to administer the surveys directly to the respondents.

A cell phone service provider has 14,000 customers.Recently,the sales department selected a random sample of 400 customer accounts and recorded the number of minutes of long distance time used during the previous billing period.The data for this variable is considered to be nominal since the values are based on sample data.

Stratified random sampling is the same thing as simple random sampling.

A variable,i.e. ,the length of time it takes for an employee to complete an assembly procedure at an automotive plant,is a ratio level variable.

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

In election years,the polls that are conducted by such companies as Gallup and Harris typically employ stratified random sampling to reduce the number of people that will need to be surveyed.
