Analysing two scale variables
Part 4: Reporting
If we combine all the reporting bits from the example, the full report for this variable, might have looked something like:
HRM is interested to know if the beginning salary can be used to predict the current salary. From a sample of employees the scatterplot in Figure 1 was produced.
As can be seen Figure 1 it appears that there is an upwards correlation between the beginning and the current salary.
The result of the regression indicated that the two variables have a significant very strong correlation, F(1, 472) = 1622.12, p < .001, R2 = .775.
As was expected a high beginning salary correlates with a high current salary. The beginning salary could therefor be used to predict someone’s current salary. An example of this will be discussed in the next paragraph….
Note the final paragraph explains the some-what technical results into more understandable English, something many readers would often appreciate.
We have not actually discussed how the beginning salary can be used for a prediction. This will be discussed in the bonus section.
