Question
Use the following information to answer the next seven exercises: 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 starting the treatment. Two researchers each follow a different set of 40 AIDS patients 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; 3: 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 17. Determine what the key term data refers to in the above example for Researcher A. 18. List two reasons why the data may differ. 19. Can you tell if one researcher is correct and the other one is incorrect? Why? 0. Would you expect the data to be identical? Why or why not? 1. How might the researchers gather random data?Explanation / Answer
From the given data,
The key kerm for collecting data by researcher A is collecting data of aids patients from start of medicine until their death. The data in the form of months.
Reasons behind data difference may be data sample , data analysis and questionnaire schedules.
We can't compare research between A and B. We can test research between A and B, basing on the test cases we can eliminate bad results.
The data shouldn't be identicial, but data should be similar. Since both researchers not implementing same method on identicial data sets. They are using different methods to set the hypothesis.
Gathering of information depends on different resources available to the researcher, the researcher could gather information from primary sources or secondary sources.
