Determine whether the following sampling is dependent or independent. Indicate whether the response variable is qualitative or q
uantitative. A researcher wishes to compare personality types of married mathematicians and their spouses. She obtains a random sample of 685 such couples who take a personality inventory and determines each spouse's personality type. 1. Determine whether the following sampling is dependent or independent.
A. The sampling is dependent because an individual selected for one sample does not dictate which individual is to be in the second sample.
B. The sampling is independent because an individual selected for one sample does dictate which individual is to be in the second sample.
C. The sampling is dependent because an individual selected for one sample does dictate which individual is to be in the second sample.
D. The sampling is independent because an individual selected for one sample does not dictate which individual is to be in the second sample.
2. Indicate whether the response variable is qualitative or quantitative.
A. The variable is qualitative because it is an attribute classification.
B. The variable is quantitative because it is an attribute classification.
C. The variable is quantitative because it is an numerical classification.
D. The variable is qualitative because it is an numerical classification.
Independent samples are samples that are selected randomly so that its observations do not depend on the values other observations. Thus, this sampling is independent. The sampling is independent because an individual selected for one sample does not dictate/affect which individual is to be in the second sample.
The variable is qualitative because it is an attribute classification. A qualitative variable are variables that are not numerical. It describes data that fits into categories (personality type).
Based on the given scenario above wherein the quality control analyst just inspects the first 100 items produced that day in order to avoid staying after work, the sampling method that she used is the CONVENIENCE SAMPLING METHOD. Hope this helps.
