Question
2.2 For each of the following situations, identify the measure of central tendency (mean, median, or mode) that would provide the best description of the "average" or most representative score. Please explain your choice: a. A researcher asks each individual in a sample of 50 adults to name his/her favorite season (summer, fall, winter, spring). b. An insurance company would like to determine how long people remain hospitalized after a routine appendectomy. The data from a large sample indicate that most people are released after 2 or 3 days but a few develop infections and stay in the hospital for weeks. c. A teacher measures scores on a standardized reading test for a sample of children from a middle-class, suburban elementary school.Explanation / Answer
a) Mode, because the data is in nominal measurement scale.
b) Median, because the objective of the study is consider the number of days people remain in hospital after a routine appendectomy (this divides the data into two parts , i.e. before and after)
c) Mean, because the data is in interval or ratio measurement scale, and for this type of data, mean is best measure
