12. Selecting a measure of central tendency Suppose you collect a sample of 1,000 people. For each person in your sample, you have measured a value for each of the variables listed in the first column of the following table. For each variable, select which of the measures of central tendency are appropriate to use to describe your sample's values for that variable. Check all that apply.

A researcher randomly selected n = 30 drivers who were issued speeding tickets in a city. There are four variables in this data set: (1) ID number, (2) age, (3) sex, and (3) size of the car that s/he drove when s/he got the speeding ticket. *Sex (1 = Males, 2 = Females); Size_car (1 = Small, 2 = Medium, 3 = Large).

1. Researchers study the impact of internalized bias on patient care. Nurses complete a survey which determines a score for their internalized bias from 0-100. Without knowing the internalized bias score, patients are asked to rank the subsequent care they receive from the nurse as poor, fair, good or exemplary. In this study your independent variable is measured at what level of measurement? Ratio Ordinal Nominal Interval 2. A study examines the relationship between interpersonal violence and health in women....
how many levels does this have? i will be the same as in Phase I and sometimes it will be different. In Phase m, you will be given a memory judgment task: You ill be asked if you recal a target in the Phase lI test. You should remember that you recall an iterm better when the context is the same and you should when the context is different. forget that you recall an iterm Instructions If you have logged...
