The researchers wonder whether Design Assistance (Q5 – ordinal, pseudo-interval) is, on average, equally desired as Assembly Assistance (Q7 – ordinal, pseudo-interval), which test is appropriate?
Paired Samples Test
The researchers wonder whether, on average, firms are more interested in Technical Assistance (Q4 – ordinal, pseudo-interval), or in the Assembly Assistance (Q7 – ordinal, pseudo-interval), which test is appropriate?
Paired Samples Test
When investigating the H0 that the average score on the three variables Q4, Q5 and Q7 is the same, to investigate the H0 properly, we need to perform…
Pearson correlation
Researchers suspect: The more high-tech the firm is, the less interested it will tend to be in assembly assist.
Which test is appropriate?
