Correlation Flashcards
what is a correlation study investigating
relationships between covariables
what’s a positive correlation
as one covariable increases, the other increases
what’s a negative correlation
as one covariable increases, the other decreases
what’s no correlation
covariables don’t appear to be relation
what’s a research question
broad question about a concept being investigated
what are research aims
identifying a specific concept within the research question
“to investigate whether…”
how do you operationalise variables
all covariables must be expressed as numbers
can you have hypotheses in correlations
yes
give an example of a 2 tailed correlational hypothesis
there will be a significant correlation between covariables x and y
give an example of a one tailed correlational hypothesis
there will be a significant positive correlation between covariables x and y
what’s primary data
data gathered directly from participants by researcher
what’s secondary data
data already gathered by someone other than the researcher
what type of graph do you use for corrections
scatter graph
what are correlation coefficients between
-1 and 1
what’s the correlation if the coefficient is +1
perfect positive correlation
