Practice Test
The following questions will help you to assess your comprehension of the concepts in chapter 10.

This activity contains 32 questions.

	Reliability can range from _________(no reliability) to ____________ perfect reliability.   -1-1 0-100 0-1 -1-10

	Which of the following would be an example of a study that is low in reliability?   Questionnaire scale on creativity Achievement test Aptitude test Objective test

	A test was given to students in September and again in December to compute a correlation between scores at these two times. What is this an example of?   Split-half KR-20 Internal consistency Test-retest

	This type of validity is particularly important in achievement and aptitude testing   Predictive validity Content validity Face validity Concurrent validity

	Which two types of validity are often referred to together as criterion-related validity?   Concurrent and predictive Predictive and face Face and content Content and predictive

	What is an advantage to using standardized tests?   Highly reliable Can locate levels of individual or class performance All of the above Cover a wide range of student performance levels

	What is an advantage that both standardized and criterion-referenced tests share?   Measure what students are actually learning in school, not just ability Teachers can be assumed to be helping students do well Ability to use multiple test formats; multiple choice, essay, ect ... They don't share any common advantage

	The best strategy in achievement testing is to give students ______________.   Standardized and criterion-referenced tests Standardized tests Researcher made and standardized or criterion-referenced tests Researcher made tests

	What is a good way to increase reliability?   Use authentic assessments the observers should know hypothesis of the study before beginning Have two observers Create your own scale

	An overall reliability of ___________ and an occurrence reliability of _____ are usually considered reasonable minimums.   .80 .70 .75 .80 .70 .80 .50 .75

	What is the best way to reduce the possibility of false negative error without increasing the chance of false positive error in correlational or experimental research?   Have 2 observers Increase the number of subjects Use subjects of the same sex Decrease the number of subjects

	A good design and an important problem do not automatically make a good study.    True  False

	If a researcher tried to correlate two unreliable measure, the chance of finding a correlation would be great, if the true relationship existed between the variables supposedly measured.    True  False

	There is only one correct way to compute reliability    True  False

	Internal consistency measures tend to show lower reliabilities than do correlational measures of reliability.    True  False

	Scales with few items tend to have higher reliabilities than scales with more items    True  False

	Scales given to young students are usually higher in reliability than tests given to older students.    True  False

	A measure may be reliable, but that does not mean that it measures what it is supposed to measure.    True  False

	There is no numerical criterion of validity.    True  False

	Achievement and aptitude tests are the most commonly used measure in school research.    True  False

	It is not seen as legitimate for teachers to "teach to the test" in authentic assessment.    True  False

	When we wish to use a test as a covariate, reliability is critical, and a standardized or criterion-referenced test is usually best.    True  False

	Speed tests tend to be high in reliability    True  False

	A good item on a test is one that either everyone passes or everyone fails.    True  False

	In general, it is better to use a well-established scale than attempt to create a new one.    True  False

	Observers should never be told the study hypotheses because of the possibility that this will lead to systematic bias.    True  False

	As your sample gets bigger, it takes even bigger increases to get further increases in statistical power. Basically, each additional subject does add less to statistical power.    True  False

	A teacher rates her students on class participation. Rather than marking down as each student participates, she relies on her memory of observations and gives a final overall participation grade for her students at the end of each quarter. She was afraid that she might not notice some of the times when students participate and forget to calculate them into their grade. In order to test the reliability of her scoring, she decided to have another observer come in and record how many times each student participated. After comparing her results with the reports they agreed 60 times and disagreed 55 times. Compute the teacher's reliability by using the formula: Reliability = Agreements Agreements + Disagreements How reliable was this teacher's method?   To create paragraphs in your essay response, type <p> at the beginning of the paragraph, and </p> at the end.

	A survey was given to students in fourth grade and in eighth grade to determine how prevalent bullying is in their school. The questionnaire consisted of several open ended response questions. What might you predict the reliability of the two surveys to be?   To create paragraphs in your essay response, type <p> at the beginning of the paragraph, and </p> at the end.

	Create a chart to compare/contrast the different types of validity. Be sure and explain each type by using examples.   To create paragraphs in your essay response, type <p> at the beginning of the paragraph, and </p> at the end.

	Give three examples of authentic assessments you could implement in your classroom.   To create paragraphs in your essay response, type <p> at the beginning of the paragraph, and </p> at the end.

	In testing children today, which approach do believe is the most appropriate? Standardized tests, criterion-referenced tests, authentic assessments, teacher-made tests, etc.   To create paragraphs in your essay response, type <p> at the beginning of the paragraph, and </p> at the end.
