7. What level of measurement is the variable highest social work degree received ? Justify your response .What other ways of operationalizing the variable would produce different levels of measurement ? Explain
Explanation / Answer
6. The reasearch hypothesis is as follows:
There are several arguments whether admitting to a preschool below 3 years has something to do with parents' occupation. One reseracher claims that children whose parents are into service are more keen to put babies into preschool at 3 years. The nominal level independnet variable is occupation and ratio level dependnet variable is age. For this purpose, reseracher collects random samples of preschool children at their age of admission and note their parents' occupation. Descriptive statistics corresponding to each occupation would generate meaningful results.
