A variable that is not directly measured but can affect the results
confounding variable
Variable that is manipulated variable
independent variable
The response variable
dependent variable
Type of measurement with only two options
nominal
Type of measurement that uses ranking without true 0
ordinal
Type of measurement that has equivalent value increments with true 0
interval
type of measurement with true 0 and continuous values
ratio
When would you use a factorial design
when there are multiple independent variables being studied
what is a between subject design
The participants only complete all conditions
what is a within subject design
participants do all conditions
When do you use a chi square goodness of fit
when there are only two variables
when do you use a chi square test of independence
when there are multiple values
if the statistical value found is greater than the critical value, what conclusion can you
make
reject the null hypothesis
what is the observed level of significance referred as
alpha value
If the Null is true and you reject the null, what error has been made
Type 1 error
When the Null is false and you reject the null
correct rejection
when the null is true and you fail to reject the null
correct decision
When the null is false and you fail to reject the null
type II error
when are ttests used
when averages are compared
What do you need to reject the null
a pvalue less than your alpha value or a statistical value greater than the critical value
What is an outlier
an extreme data point that causes a skew in the data
When do you calculate a correlation
when you have two continuous variables
what are the benefits of using surveys
there is a large sample size
