question
The Theory-Data Cycle Her findings add further support to the theory.
answer
After studying a proposal by Tversky and Koehler (1994) that the probabilities assigned to events vary based on descriptions of the events, Franchesca designs a study to examine how pairs of lab partners perceive their relative contribution to joint projects.

question
three Variables—Men and women, stressed and unstressed, and the number of decision tasks performed are all variables.
answer
Reading the news on the Internet, Johan comes across the headline, "When Stress is Increased, Men Rush Ahead, Women More Cautious." (This headline is based on a study conducted by Lighthall et al., 2011.) In this study, men and women were asked to perform a decision task as many times as possible in a set period, in a stressed or unstressed condition.

question
It is a confound. Interrogating Causal Claims—Poverty covaries with school lunch consumption and may be an alternative explanation for the obesity.
answer
A recent headline read, "School Lunches Make Kids Fat." The article cited a study comparing children at two schools. The school with the lower obesity rate had few children who ate school lunches. The other school had a greater percentage of obese children and most of these children ate school lunches.

What role does poverty play in this study? 1. It is an independent variable. 2. It is a confound. 3. It is a dependent variable. 4. It is a false alarm.

question
Their ratings were not the same for any individual child. Scatterplots Can Show Interrater Agreement or Disagreement—It is possible to have high interrater reliability without agreeing on any one child. However, different criteria or observation of different situations can cause low interrater reliability.

Lorenzo is studying aggression in children. First, a questionnaire about their own aggression is administered to the children. Then the children are observed while at play and instances of aggression are recorded. The results of these two parts of the study are compared. When two sets of observations made during the same time period are compared, there is low interrater reliability. Which of these should not be considered as a possible cause of this? 1. The observers were observing two different parts of the play area, one supervised, the other not. 2. Their ratings were not the same for any individual child. 3.

The cloud of points would slope downward from left to right. Using the Correlation Coefficient r to Evaluate Reliability—A negative correlation coefficient means that there is a downward (from left to right) slope. The lower scores of the coin rotation task correspond to quicker turning and higher scores on the tapping task correspond to faster tapping, producing a negative correlation.
answer
Mendoza et al. (2009) introduced a coin rotation task as a convenient test of motor dexterity. It involves timed completion of twenty 180° rotations of a nickel using the thumb, index, and middle fingers. The results were compared to the results of another widely used test of motor dexterity, the finger-tapping task, in which participants tap their index fingers as many times as possible in 10 seconds. The statistically significant results showed r = -.400. What would a scatterplot of these results (coin rotation scores on the x-axis, finger-tapping scores on the y-axis) look like? 1. The cloud of points would have no slope at all. 2. The cloud of points would slope upward from left to right. 3. The cloud of points would slope downward from left to right. 4. There isn't enough information given to determine this.
question
declared major in college Scales of Measurement—Categorical or nominal variables are those that fit into categories. Majors in college, such as psychology, business, or biology, are categorical.
answer
Which of the following is a categorical variable? 1. IQ score 2. blood pressure reading 3. declared major in college 4. current age
question
divergent validity Convergent and Discriminant Validity—The coin rotation task should correlate strongly with other tests of motor dexterity, but should not correlate strongly with measures of other traits. Grip strength is related to motor functioning, but does not capture dexterity, so this is discriminant evidence for validity.
answer
Mendoza et al. (2009) introduced a coin rotation task as a convenient test of motor dexterity. It involves timed completion of twenty 180° rotations of a nickel using the thumb, index, and middle fingers. The results from this task are compared with the results from a measure of global upper-extremity strength, grip strength. These results were found to be not significant. What empirical way of assessing construct validity is being used? 1. face validity 2. predictive validity 3. divergent validity 4. convergent validity
question
convergent validity Convergent and Discriminant Validity—As both of these measures are of aggression, the results of the observation should have a strong positive correlation with the results of the questionnaire. This would show convergent validity.
answer
Lorenzo is studying aggression in children. First, a questionnaire about their own aggression is administered to the children. Then the children are observed while at play and instances of aggression are recorded. The results of these two parts of the study are compared. Lorenzo plots the questionnaire scores on the x-axis and the observed instances of aggression on the y-axis of a scatterplot and determines r. What type of validity is he examining? 1. content validity 2. predictive validity 3. divergent validity 4. convergent validity
question
the measurement validity Measurement Validity of Abstract Constructs—Professor Morgan is concerned about whether the tool used to assess his teaching effectiveness actually measures that construct or some other construct.
answer
Professor Morgan questions whether the ratings he receives from his students on "teaching effectiveness" indicate how much the students learn in his class or are just based on how much his students like him. What part of the ratings is he questioning? 1. the reliability 2. the statistical significance 3. the use of an interval scale 4. the measurement validity
question
predictive validity Predictive and Concurrent Validity—The concern is the lack of predictive value of these tests. The test scores did not predict the freshman year GPA.
answer
Some colleges no longer require the SAT I or the ACT tests, instead basing their admissions on other factors, such as high school GPA. A large reason that they have done this is that they have found a low correlation between the scores on the tests and the students' freshman year GPA. What type of validity was missing and led the colleges to change admissions criteria? 1. face validity 2. predictive validity 3. discriminant validity 4. content validity
question
observational measures Three Common Measurement Types—The researcher is recording the observational behaviors of the children by recording acts of aggression.
answer
In a study of aggression in children, the researcher watches a group of children on the playground and records the number of instances of physical or verbal attacks. Which category of measured variable is this researcher using? 1. self-report measures 2. observational measures 3. physiological measures 4. neuropsychological measures
