distribution where there are two modes instead of one, where there are two peaks on the curve. Two central clusters instead of just one.
What is a bimodal distribution?
100
scores with highest frequency are on the right side of the graph in what kind of skew?
What is negative skew?
100
the p stands for what in a p value
What is probability
100
the first step in the process of research
What is identifying a research problem
100
studies research problems in which an issue needs to be explained
What is quantitative research
200
Higher and narrower than the mesokurtic or normally peaked curve.
What is a leptokurtic distribution?
200
scores with the highest frequency are on the left side of the graph in this type of skew
positive skew
200
rejecting the null hypothesis when it was true
What is type 1 error
200
second step in the process of research
What is reviewing the literature
200
studies research problems in which the problem needs to be explored
What is qualitative research
300
Mesokurtic distribution is a standard distribution.
What is a mesokurtic distribution?
300
these allow us to describe and summarize observations
What is descriptive statistics
300
the square root of the variance
What is standard deviation
300
experimental, survey and correlational, and mixed method associated with what type of research?
What is quantitative research
300
the hypothesis that you are trying to prove by getting enough evidence to reject the null hypothesis
What is alternative hypothesis
400
Platykurtic distributions are lower and wider (flatter) than a mesokurtic distribution
What is a platykurtic distribution?
400
non-directional hypothesis
What is two-tailed hypothesis
400
the variable that changes based on the intervention
What is dependent variable
400
in a research experiment, the hypothesis that you are trying to disprove. "No difference"
What is null hypothesis
400
standard deviation squared
What is variance
500
68.26%
What is the percentage of the normal distribution that is between negative 1 and positive 1 standard deviations above the mean?
500
allow us to generalize results observed from a small sample of a population to the greater population
What is inferential statistics
500
isn't changed by the other variables measured.
What is independent variable
500
issue, concern or controversy that the investigator presents and justifies in a research study
What is a research problem
500
a variable that "stands between" the independent and dependent variables and exercises an influence over the dependent variable apart from the independent variable
