3. With hypothesis testing we are setting up a null-hypothesis
– the probability that there is no effect or
relationship –
4. With hypothesis testing we are setting up a null-hypothesis
– the probability that there is no effect or
relationship – and then we collect evidence that leads
us to either accept or reject that null hypothesis.
5. As you may recall, a Pearson Product Moment
Correlation or simply Pearson Correlation is a tool that
makes it possible to statistically test the relationship
between or (for the purposes of this presentation) the
independence of two continuous variables.
6. As you may recall, a Pearson Product Moment
Correlation or simply Pearson Correlation is a tool that
makes it possible to statistically test the relationship
between or (for the purposes of this presentation) the
independence of two continuous variables. By
continuous we mean a number that can take any value
between two points (e.g., weight between 150 to 250
pounds).
7. Here is a template for writing a null-hypothesis for a
Pearson Correlation:
8. Here is a template for writing a null-hypothesis for a
Pearson Correlation:
There is no statistically significant relationship between
the [insert variable] and [insert variable].
9. Here is a template for writing a null-hypothesis for a
Pearson Correlation:
There is no statistically significant relationship between
the [insert variable] and [insert variable].
With a question of independence, the
null-hypothesis is what is sought after.
