With your classmates, brainstorm some ways you could overcome these problems if you needed to conduct a phone or mail survey.

Short Answer

Expert verified

1. To find out who is answering from the other side, ask the respondents for any government-issued photo ID to verify their identification.

2. To ensure that all emails are replied, the interviewer must send reminders to respondents to remind them to respond to the email, and the interviewer must also phone respondents at various times if the call is unanswered.

3. To ensure that no one is left out of the survey, the interviewer should create a spreadsheet with the details of the respondents, including which respondents have entered their responses and which respondents have yet to be questioned.

Explanation

The approaches listed below may assist you in overcoming the challenges of conducting a phone or postal survey:

Only then will this strategy be useful if the list of phone numbers or email addresses is complete and includes all of the subjects in the population.

People who do not answer the phone should be contacted at various times when they are at home to receive the call, and mail reminders sent on weekends may receive a positive response.

To overcome interpretation concerns, simple questions must be asked using suitable wording and phrasing so that the question's objective is obvious.

To solve interpretation concerns, ensure that simple inquiries are asked using proper wording and phrasing so that the question's intent is obvious.

The options in a closed ended question must allow the respondent to provide the response of their choice.

1.11 You are going to use the random number generator to generate different types of samples from the data.

This table displays six sets of quiz scores (each quiz counts 10 points) for an elementary statistics class.

Instructions: Use the Random Number Generator to pick samples.

1. Create a stratified sample by column. Pick three quiz scores randomly from each column.

鈼 Number each row one through ten.

鈼 On your calculator, press Math and arrow over to PRB.

鈼 For column 1, Press 5:randInt( and enter 1,10). Press ENTER. Record the number. Press ENTER 2 more

times (even the repeats). Record these numbers. Record the three quiz scores in column one that correspond

to these three numbers.

鈼 Repeat for columns two through six.

鈼 These 18 quiz scores are a stratified sample.

2. Create a cluster sample by picking two of the columns. Use the column numbers: one through six.

鈼 Press MATH and arrow over to PRB.

鈼 Press 5:randInt( and enter 1,6). Press ENTER. Record the number. Press ENTER and record that number.

鈼 The two numbers are for two of the columns.

鈼 The quiz scores (20 of them) in these 2 columns are the cluster sample.

3. Create a simple random sample of 15 quiz scores.

鈼 Use the numbering one through 60.

鈼 Press MATH. Arrow over to PRB. Press 5:randInt( and enter 1, 60).

鈼 Press ENTER 15 times and record the numbers.

鈼 Record the quiz scores that correspond to these numbers.

鈼 These 15 quiz scores are the systematic sample.

4. Create a systematic sample of 12 quiz scores.

鈼 Use the numbering one through 60.

鈼 Press MATH. Arrow over to PRB. Press 5:randInt( and enter 1, 60).

鈼 Press ENTER. Record the number and the first quiz score. From that number, count ten quiz scores and

record that quiz score. Keep counting ten quiz scores and recording the quiz score until you have a sample

of 12 quiz scores. You may wrap around (go back to the beginning).

Use the following data to answer the next five exercises: A pair of studies was performed to measure the effectiveness of a new software program designed to help stroke patients regain their problem-solving skills. Patients were asked to use the software program twice a day, once in the morning and once in the evening. The studies observed 200stroke patients recovering over a period of several weeks. The first study collected the data in Table 1.31. The second study collected the data in Table 1.32.

Patients who used the software were also a part of an exercise program whereas patients who did not use the software were not. Does this change the validity of the conclusions from Exercise 1.31?

1.21 You are concerned about the effects of texting on driving performance. Design a study to test the response time

of drivers while texting and while driving only. How many seconds does it take for a driver to respond when a leading

car hits the brakes?

a. Describe the explanatory and response variables in the study.

b. What are the treatments?

c. What should you consider when selecting participants?

d. Your research partner wants to divide participants randomly into two groups: one to drive without distraction and

one to text and drive simultaneously. Is this a good idea? Why or why not?

e. Identify any lurking variables that could interfere with this study.

f. How can blinding be used in this study?

A study was done to determine the age, number of times per week, and the duration (amount of time) of residents using a local park in San Antonio, Texas. The first house in the neighborhood around the park was selected randomly, and then the resident of every eighth house in the neighborhood around the park was interviewed.

鈥淒uration (amount of time)鈥 is what type of data?

a. qualitative(categorical); b. quantitative discrete; c. quantitative continuous

The graph in Figure 1.15shows the number of complaints for six different airlines as reported to the US Department of Transportation in February 2013. Alaska, Pinnacle, and Airtran Airlines have far fewer complaints reported than American, Delta, and United. Can we conclude that American, Delta, and United are the worst airline carriers since they have the most complaints?
