df = n-2
What is the degrees of freedom for a correlation?
100
This correlation just needs one ordinal variable.
What is Spearman's correlation?
100
df = (k-1)
What is the degrees of freedom equation for a Chi-squared goodness of fit test?
200
It's when we find no significant effect when we probably should have.
What is a type two error?
200
A statistical method that uses sample data to evaluate the validity of a hypothesis about a population parameter.
What is hypothesis testing?
200
This correlation needs one interval/Ratio variable and one nominal variable.
What is a Point-Biserial correlation?
200
This test for evidence of a relationship between two variables
What is the Chi-squared test for independence?
300
This is a parametric test that allows you to test the null hypothesis for a single sample.
What is a Z test?
300
Number of agreements __________________ X 100 Number of answers
What is the equation for interrater Reliability?
300
Ethical principles for research involving humans.
What is the Belmot report?
300
It tells us how much of an effect the variables had together.
What is the coefficient of determination?
300
Measures the strength of a matrix bigger than a 2x2
What is Cramer's V
400
This type of statistic only uses nominal and ordinal data.
What is non-parametric statistics?
400
The amount of scores in a sample that are free to vary.
What is the degrees of freedom?
400
Interval/Ratio data large enough sample size random sampling normal distribution standard deviation and mean known sample vs. Population
What is the conditions you should have to use a Z test?
400
It tells us the strength, direction, and whether or not we have a linear equation.
What is Pearson's r?
400
It compares the observed frequencies from the data with the expected frequency predicted by the null hypothesis.
What is a Chi-squared goodness of fit test?
500
This is the probability that a test will lead to a type one error.
What is the alpha level?
500
Measures the amount of co-variability between two variables.
What is the Sum of Products?
500
They monitor human research.
What is the Institutional Review Board?
500
Serves the purpose of seeing if there is a relationship between two variables.
What is the correlation method?
500
We don't want our sample to do this in a goodness of fit test
