Question
Problem statement: One of the relationships of interest in research of patients who demonstrate functional disturbances due to suspected cervical root lesion and experience pain and sensory symptoms. A study was conducted to investigate the relationship between a patient’s height (cm) and the peak spinal latency (Cv) of the somatosensory evoked potentials (SEPs). The study seeks to investigate whether Cv can be predicted from a presenting patient’s height. Is prediction possible?
The appropriate test for this problem is:
t test for one sample
t test for dependent samples
t test for independent samples
one-way ANOVA
repeated measurements ANOVA
correlation analysis
linear regression
multiple regression
one-variable chi-square
two-variables chi-square
Problem statement: A study was conducted to compare the levels of job satisfaction of employees working the toll booths at SR 408, SR 528, SR 417, SR 429 and SR 414. Each group of toll employees were administered a job satisfaction survey. Will the job satisfaction be significantly different between the groups?

Explanation / Answer
1) Correlation helps us in understanding the relationship between the 2 variables i.e whether a prediction is possible.
Hence a correlation analysis is used here.
2) Here we are testing for difference in more than 2 means, but for independent populations. Hence we use a one way ANOVA here.
