A research conducts a study on the effectiveness of computer-assisted instruction (CAI) by comparing a class that uses this method with a class that does not. The researcher expects the CAI class to show greater gains in achievement. This expectation is called:

A hypothesis

A researcher wishes to determine the effects of an outdoor adventure summer camp on the self-concept of inner-city boys. Boys are randomly assigned to the summer camp and to a control situation. The experimental treat is for three months. A secondary purpose is to see if age ( ages 6,9, and 12) affects the relationship of the camp effects and self-concept. In this study, self-concept is an example of a-

When the experimenter has a reasonably high expectation concerning the relationship that exists between the variable, it is most appropriate to state the hypothesis in the ___ form-

A thesis was submitted with the title "A study comparing the achievement of sixth-grade students in Moscow, Idaho, instructed in health education through closed-circuit television and regular classroom procedure for a period of 16 weeks," This title is-

Type I

reject null when it's true

A limitation in a study is- These are all false

-The same as a delimitation -Prevents a study from being published or accepted by a graduate thesis committee -Of no concern because all studies have them

Plagiarism

-The words of another are used without reference to the source -The ideas of another are used without reference to the source -When in doubt if it is necessary to cite the source because the information might be considered general knowledge, it is best to do so

The only type of research that can establish cause and effect is:

Experimental

Which is the best description of the review of literature:

It is a critique of the literature that includes results and limitations of studies to establish what we currently know.

Nonparametric

statistics are used when data are nominal or ordinal or when the populations from which the observations were made are thought NOT to be normally distributed.

Parametric

statistics are used when the research data are interval or ratio and when the populations from which the observations were made are thought to be normally distributed. Randomness. More Powerful. t test: 2 mean scores ANOVA: more than 2 mean scores

Type II

Ethical charge to protect research subjects-

A researcher wishes to determine the effects of an outdoor adventure summer camp on the self-concept of inner-city boys. Boys are randomly assigned to the summer camp and to a control situation. The experimental treat is for three months. A secondary purpose is to see if age ( ages 6,9, and 12) affects the relationship of the camp effects and self-concept. The researcher states that he is aware that response to question on a self-concept scale may not always be what the person really believes. This is an example of an-

The experimental treat is for three months. A secondary purpose is to see if age ( ages 6,9, and 12) affects the relationship of the camp effects and self-concept.

Man Whitney

ORDINAL

Numbers indicate rank order of observations. Sequential Ordering. Demonstrates rank by showing difference and direction of difference 1. Bama, 2. Penn state 3. Clemson

NOMINAL

Numbers represent categories. Numbers do not reflect differences in magnitude. Numbers serve to distinguish groups. Categorical. Most rudimentary, providing only information about a difference.

RATIO

Numbers represent equal units from absolute zero. Observations can be compared as ratios or percentages. Absolute Zero. Continuous. Height and Weight, zero means it doesn't exist

INTERVAL

Numbers represent equal units or intervals from an Arbitrary Zero Point. Intervals between observations can be compared. 1. Bama (1.000) 2. Penn State (.994) 3. Clemson (.914) Zero wouldn't mean anything, just like IQ
