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.

Use the following data to answer the next five exercises: Two researchers are gathering data on hours of video games played by school-aged children and young adults. They each randomly sample different groups of 150 students from the same school. They collect the following data.

Give a reason why the data may differ.

A marriage counselor is interested in the proportion of clients she counsels who stay married.

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).

Studies are often done by pharmaceutical companies to determine the effectiveness of a treatment program. Suppose that a new AIDS antibody drug is currently under study. It is given to patients once the AIDS symptoms have revealed themselves. Of interest is the average (mean) length of time in months patients live once they start the treatment. Two researchers each follow a different set of 40 patients with AIDS from the start of treatment until their deaths. The following data (in months) are collected.

Researcher A:

3; 4; 11; 15; 16; 17; 22; 44; 37; 16; 14; 24; 25; 15; 26; 27; 33; 29; 35; 44; 13; 21; 22; 10; 12; 8; 40; 32; 26; 27; 31; 34; 29; 17; 8; 24; 18; 47; 33; 34

Researcher B:

3; 14; 11; 5; 16; 17; 28; 41; 31; 18; 14; 14; 26; 25; 21; 22; 31; 2; 35; 44; 23; 21; 21; 16; 12; 18; 41; 22; 16; 25; 33; 34; 29; 13; 18; 24; 23; 42; 33; 29

Determine what the key terms refer to in the example for Researcher A.
