Personality Psychology Chapter 3
What significance level would indicate that a researcher is 5 percent sure that they would get the result they found if the null hypothesis were true?
.05
The Binomial Effect Size Display (BESD) is a way to think about the size of what?
Correlation coefficients
Which of the following personality tests are omnibus inventories?

______ is primarily concerned with determining the significance of a single test and therefore does not do an adequate job at assessing how stable a result is across time and contexts. Researchers need to perform a ______, which is a much better indicator of the stability of a result.
NHST, replication
_____ uses p-levels to identify the ______ of the difference between two groups in an experimental design. The p-level gives the probability of getting the result one found if the _______ were true.
Null-hypothesis significance testing, significance, null hypothesis
______ is an emerging movement meant to move research closer to the ideals upon which it was founded. It focuses on improving ______ in science. Specifically, this movement promotes reporting studies that have failed and succeeded and _____ all data, materials, and methods involved in a study.
Open science; transparency, openness, and reproducibility; sharing
Rorschach test
Patients tell an analyst what they see in an inkblot.
The Thematic Apperception Test (TAT) is an example of what type of test?
Projective
In 2005 a prominent statistician published an article titled, "Why Most Published Research Findings Are False" (Ionnadis). Which of the following points support the article's claim that most published work generates findings that are false?
Researchers tend to report selected analyses rather than everything they find regardless of whether it is significant. Researchers are rewarded with grants and jobs for studies that generate findings that are interesting. There is a proliferation of small studies with weak effects. NOT, Social psychology receives more grant funding than does personality psychology. Psychological experiments are time-consuming and expensive.
Most personality tests provide what kind of data?
S data
What is the best explanation for why publication bias is a major concern for science?
Strong effects are published much more often, which leads to a literature that over-represents the strength of an effect.
Which sentence about the Binomial Effect Size Display (BESD) is false?
The BESD shows how much of an outcome we can predict from an individual measurement of difference; TRUE The BESD is a concrete display of what the correlation coefficient means in terms of specific outcomes., Squaring the correlation coefficient shows what percentage of the data can be explained by the correlation between variables; for example, a coefficient of .4 shows us that 16 percent of the data can be explained by the correlation (a rather strong effect size)., To interpret a correlation coefficient, it is enough to just use statistical significance

Often a scale is used to predict behavior, diagnosis, or category membership in new samples of participants. This process is referred to as what?
cross-validation
Why do objective tests typically have so many test items or questions?
one way to make a test more reliable is simply to make it longer
One influential study discussed in the text (Simmons, Nelson, & Simonsohn, 2011) manipulated a real dataset to show that listening to the Beatles song "When I'm 64" actually made participants younger. What questionable research practice did these researchers use to attain this result?

The ____ she calculates is the magnitude, or size, of her findings.
p-level, effect size
In the context of psychological research, what does the word "significant" mean?
A significant result is one that is unlikely to occur by chance

Place the steps used in the factor analytic method of test construction from first to last.
1. Establish a long list of objective and relevant items 2. Administer the test to a large number of participants 3. Calculate correlation coefficients between each item and each of the other items 4. Determine which items can be grouped together to form greater factors

projective test
A participant in a psychology study interprets an ambiguous picture of members of various ethnicities in order to provide data on their unconscious prejudices.
objective test
A participant in a psychology study rates how much they agree with a series of statements about their personality on a scale from 1 to 5. the Minnesota Multiphasic Personality Inventory (MMPI), a Big Five personality test, the California Psychological Inventory (CPI), NOT: the Rorschach test, the Thematic Apperception Test
Which of the following are concerns associated with the practice of null-hypothesis significance testing (NHST)?
A statistically significant result is not necessarily important or meaningful., The criterion for a significant result (p < .05) is arbitrary., A lack of a significant result is interpreted as there being no differences between experimental groups. NOT CONCERNS The p-value is easy to interpret, and its logic is easy to describe., It is expensive and time consuming to calculate the p-value.
Which sentence describes a Type I error in significance testing?
A type I error involves deciding that one variable has a relationship with another, when really it does not; A researcher conducts a study and finds a statistically significant correlation between eating pizza and aggression. In reality, there is no association between eating pizza and aggression in the population.
Which sentence describes a Type II error in significance testing?
A type II error involves deciding that one variable does not have a relationship with another, when really it does ; A researcher conducts a study and fails to find a statistically significant correlation between exercise and weight loss. In reality, there is an association between exercise and weight loss in the population.

Which of the following are arguments against using personality tests?
They can be unfair mechanisms through which institutions can control individuals. They may discourage women or members of minority groups from joining certain fields. NOT ARGUMENTS: They are biased towards identifying people who are high in the Big Five traits. They encourage employers to judge individuals based on their physical features rather than on their personality traits.
