Question

1) Which variables are quantitative? Which variables are categorical? 2) Using the data set, construct a research question. Identify at least one dependent variable and at least one independent variable. Make a hypothesis about the expected relationship between the independent and dependent variable and briefly explain why you would expect that hypothesis.

Answer 1

1.> From the given table we can say that, there are total 6 variables consisting of 1 categorical and 5 quantitative variables.

Categorical variable:-- Region.

Quantitative variable:-- BAPlus, PctPoverty, PctUrban, PctUnemp, Population.

2.> As per the given data set the best possible question would be , which factor is most and which one is least effective in unemployment of the given states !

AtAleast one Independent variable- BAPlus, PctPoverty, PctUrban.

Atleast one dependent variable- PctUnemp.

Hypothesis Testing :--

Null Hypothesis: All the factors are equivalent for the result of unemployment rate.

Against

Alternative Hypothesis: They are not equally effective for Unemployment rate.

Conclusion:--From the hypothesis we can say that, the variables responsible for unemployment rate varying for different states are not equally responsible as may be there are some crucial factors which affect the most and there might be some least responsible for that depending upon the state.
