This measures and provides valid and reliable data regarding your clients so you can pick the effective modalities of

treatment

tests

100

A measure of variability or dispersion of scores

Standard Deviation

100

This type of reliability describes the consistency of two or more raters. 

Inter-rater reliability

100

Is the following a power test or speed test:  



A timed typing test used to hire secretaries 

Speed test

100

This group does not receive the experimental Independent 

Variable 

the control group

200

In this type of design, the same subjects are used for the control condition, and then at a different time for the IV/experimental condition/s



Within groups design, AKA repeated measures or within-subject design

200

What are the three measures of central tendency?

the mean, the median, and the mode.

200

This type of reliability describes the extent to which scores on a test will differ from one use to another 

External Reliability.    note: this includes test-retest, alternate-forms, and interrater reliability. 


200

the Wechsler and the Binet are examples of what types of tests? 

Intelligence tests

200

This type of hypothesis typically states that there is no significant difference in the things being compared

null hypothesis

300

This term states that if a client scores exceptionally low or exceptionally high on a test, then the client with the low score will go up on the next administration, while the client with the high score will go down toward the mean or 

average

regression to the mean

300

What percent of the scores on a normal curve will fall between +/- 2 SD from the mean? 

95% of all scores will fall between +/- SD from the mean. 

note: 68% of scores fall between +/- 1 SD, and 99.7% of scores will fall between +/- 3 SD from the mean

300

Fill in the following statement using the words "reliable" and "valid" ...... A ____ test is not always ___ but a _____ test is always _______


A reliable test is not always valid, but a valid test is always reliable. 

300

This type of test predicts potential 

aptitude test

300

This is used when you are investigating more than one IV/experimental variable. 

Factorial Analysis of Variance 

400

If the subjects know they are being observed, we refer to the process as an ______ measure 

obtrusive or a reactive measure

400

Is a correlation of -.8 stronger or weaker than a correlation of .5? 

-.8 is stronger 

400

This type of validity assesses whether the research instrument accurately measures the theoretical concept it's designed to measure. 

construct validity

400

This test tells you if significant differences are present in the data

F test. note: ANOVA (analysis of varience/one-way) provides F values


400

When a researcher rejects a null hypothesis that is true, it is a ____ error 

Type 1 alpha error 

500

If the researcher did not manipulate the variable and you are looking at after the fact data, then the research is not a true experiment but rather an _______

ex post facto, also called causal-comparative design

500

Label the following sections by percentages 

2.14%, 13.59%, 34.13%, 34.13%, 13.59%, 2.14%

500

This is a type of criterion validity that defines how well a measure correlates with a criterion measured at the same time 

concurrent validity 

500

This is the most common nonparametric test

chi-square.  This test is used when the population is not necessarily 

normal

500

This is approximately the middle 50% of where the scores fall. It is the 25th-75th percentile, or Q3-Q1 =
