Description
COURSE FORMAT:
This is a 1.5hr online course which will offer an introduction to
correlation. Correlations statistics help us understand and describe
how a change in one variable is associated with a change in another
variable. Correlations measure the strength and the direction of how two
variables change together. The course will mix teaching with
demonstrations and hands-on exercises.
PREREQUISITES:
The ‘SPSS’ courses are designed to be undertaken in order. Participants
must have attended the SPSS for Beginners course prior to applying for
the SPSS Advanced Parts 1 & 2 courses.
CONTENT:
During this session, you will be introduced to:
• The Pearson correlation - The Pearson Correlation coefficient is
a
parametric test that measures how much the scores of two continuous
variables vary together.
• The Spearman correlation – The Spearman correlation is the
nonparametric equivalent to the Pearson correlation and is used when the
data is ordinal or when it is not normally distributed.
• Partial correlation - Partial correlation is a measure of the
strength and direction of a linear relationship between two continuous
variables whilst controlling for the effect of one or more other
continuous variables also known as 'covariates'.
• Point-biserial correlation - A point-biserial correlation is used
to measure the strength and direction of the association between one
continuous variable and one dichotomous variable (i.e. male/female,
yes/no etc.).
Learning outcomes:
During this training, you will:
• Learn the different assumptions the data must meet for
correlations.
• Learn how to conduct the above correlations using SPSS.
• Be able to interpret the results from the tests.
