## r = 00 is best described as

 a perfect correlation. A positive correlation. A weak correlation. no correlation.

## Pearson’s r is best used with what types of scales?

 Ratio and interval scales. Nominal and ordinal scales. Interval and nominal scales. Ratio and ordinal scales.

## Reliability most commonly measured using which of the following metrics?

 Pearson’s Product Moment Kuder-Richardson 20 Coefficient Alpha Standard Error of Measurement

## Research has proven that the Best Achievement Test in America had poor internal consistency. What does that mean?

 The different versions of the test do not produce the same responses. The test is not produce the same results across time. The test, when split and half and compared, does not produce the same results. The test items do not repeatedly measure what they say they measure.

## Mr. Jones, the classroom teacher, administers a test to Joey in September and then again in October. Joey’s scores are one point off. This test could be said to have

 Split half-reliability Alternate forms reliability Interrater reliability Test-retest reliability

## Mrs. Rodriguez administers version A of an achievement test in September and then version B in May to determine progress for IEP reporting. Researchers must determine _____ reliability in order to ensure that version A is the same as version B.

 Split half-reliability Alternate forms reliability Interrater reliability Test-retest reliability

## Mark and Eve collect data on the same student using the same assessment and find their data is almost exactly the same. It could be said that Mark and Eve have

 Test-retest reliability Interrater reliability Alternate forms reliability Split half-reliability

## This formula is used to check consistency across items of an instrument with right/wrong responses.

 Kuder-Richardson 20 Pearson’s Product Moment Coefficient Alpha Standard Error of Measurement

## This formula is to check consistency across terms of an instrument with responses with varying credit.

 Product Moment Kuder-Richardson 20 Standard Error of Measurement Coefficient Alpha

## Mrs. Morgan reviews an assessment that has a correlation coefficient of .45. Should Mrs. Morgan use this test? Why?

 No; a correlation coefficient must be at .80 to be considered reliable. No; the correlation coefficient is too low. Yes; the correlation coefficient is considered adequate. Yes; if the test was published, it must be reliable to use.

## Test A has a standard error of measurement of 4.3 and Test B has a standard error of measurement of 1.3. Which test should be administered to ensure the best obtained score as possible?

 Neither. Either test would be reasonable to give. Test A. Test B.

## Given the following information, determine the standard error of measurement. Standard deviation = 10.83, r = +.83.

 17 Unable to be determined. 4.47 .41

## Given an obtained score of 87, a standard error of measurement of 3.5 and a correlation coefficient of .83, which of the following would be the correct confidence interval?

 86-88 86.17 – 87.83 84 – 90 83.5 - 90.5

## Given the following information, estimate the true score. Mean of the group = 76, correlation coefficient = .83, obtained score = 81, standard deviation = 2.23

 71.85 -64.85 80.15 11.15

## What happens to the range of scores when comparing obtained and true scores?

 The true score provides a wider confidence interval. The true score provides a narrower confidence interval. There is no difference. The obtained score provides a narrower confidence interval.

## When a test actually measures what it purports to measure, we say that it has good

 Validity. Correlation. Reliability. Variance.

Suppose you created a new measure of reading comprehension and you wanted to test its validity. Therefore you compare the results of your new measure to existing validated measures of reading comprehension and find that your measure compares well with these other measures. We could then say that your new measure has good____.

 reliability concurrent validity criterion-related validity content validity

## A test is said to accurately assess specific psychological and personality traits, psychological concepts, attributes, and theoretical characteristics. This assessment is likely to have good

 predictive validity. construct validity. content validity. concurrent validity.

## Mrs. Beth noticed that many of the students in her class who are Latino answered the same questions wrong when administering a standardized assessment. Mrs. Beth may be noticing _____ in the test creation.
