Test 2 Practice Test (Part 1)

Matching Vocab: Quantitative Research This type of research is expressed in numbers & graphs. It is driven by numerical data that is used to test or confirm theories. Qualitative Research This type of research is expressed in words and usually gathered through observation or interviews. It is used to understand concepts, thoughts or experiences. Fill in the blanks below (use the word bank at the bottom if needed): Conceptual definitions work to describe the idea of what we are measuring, for example, student graduation. Operational definitions are used to show how we are going to measure something, for example, whether a student graduates or not.Continuous variables have a number value, they are ordered in a certain way, and they are usually used alongside quantitative research questions. Categorical variables contain a finite number of categories or distinct groups. This data does not have a logical order. Nominal scales describe a variable with categories that do not have a natural order or ranking. Ordinal scales describe variables where the order matters but the difference between them does not. Ratio scales have all the same properties as an interval scale but there is a clear definition of 0. Interval scales describe variables where the order matters and the difference between the two values is meaningful. Matching again :) Reliability Consistency of Scores Validity Extent to which we are measuring what we claim to be measuring Face Validity Does your measure pass the eye test? Content Validity does our scale capture what we claim to be measuring? Concurrent Validity indicates the amount of agreement between two types of measures taken at the same time Predictive Validity indicates the amount of agreement between one measure and another one taken at a future time Does increasing the amount of money football teams spend per athlete increase their player's 40 yard dash times? Identify the independent and dependent variables in this research question, and identify the scales on which they are measured (i.e., nominal, ordinal, interval, or ratio). Please explain why. Does increasing the amount of money football teams spend per athlete increase their players 40 yard dash times? How might you test if 40 times are a reliable measure of an athlete's ability? Does increasing the amount of money football teams spend per athlete increase their player's 40 yard dash times? A researcher finds that football teams that spend more money per athlete than other teams have athletes with faster 40 times, on average. What is a likely confound? Explain your answer. Provide a conceptual and operational definition of "a good teacher." Please type your answer below.
