A process of steps used to collect and analyze information to increase our understanding of a topic or issue.
What is research?
100
A summary of the major aspects of a study or article, conveyed in a concise way.
What is an abstract?
100
The sum of all scores divided by the number of scores.
What is the mean?
100
N-1.
What is degrees of freedom?
200
Identifying a research problem; reviewing the literature; specifying a purpose for research;specifying a purpose; collecting data; analyzing and interpreting the data; reporting and evaluating the research.
What is the process of research?
200
A statement that advances the overall direction or focus for a study.
What is a purpose statement?
200
The average of each score's squared difference from the mean.
What is the variance?
200
Used when the variable of interest is a nominal variable.
What is a chi-squared test?
300
Experimental; correlational; survey.
What is quantitative designs?
300
A characteristic or attribute of an individual or an organization that researchers can measure or observe and varies among individuals or organizations studied.
What is a variable?
300
The square root of the variance.
What is the standard deviation?
300
Occurs when the researcher fails to reject the null hypothesis when an effect actually occurs in the population.
What is a type II error?
400
Grounded theory; ethnography; narrative.
What is qualitative designs?
400
Attributes or characteristics that researchers cannot directly measure because their effects cannot be easily separated from those of other variables.
What is confounding variables?
400
A score that describes a score in terms of how much it is above or below the average.
What is a Z score?
400
When the critical region for rejection of the null hypothesis is divided into two areas at the ends of the sampling distribution.
What is a two-tailed test of significance?
500
Mixed methods; action research.
What is combined designs?
500
When there is no relationship independent and dependent variables or no difference between groups of an independent variable and a dependent variable.
What is a null hypothesis?
500
When you reject the null hypothesis when in fact the null hypothesis is true.
What is a type I error?
500
When the region for rejection of the null hypothesis is placed only at one end of the distribution.
