Classify the levels of the data, meaning, tell me if the data are nominal, ordinal, interval, or ratio (pick just one). 2. Calculate measures of central tendency (mean, median, and mode) and variability (range, SD, and variance) (attached the SPSS table below). 3. Write one null and one research hypotheses for the data above. 4. This question has multiple parts: a. Create normal and binomial curves/graphs or run the test of normality to show if the data is normally distributed or not. Include the graphs/curves/table below. b. Interpret what you see going on with the graphs/curve/table (are they normally distributed or not? Why or why not). 5. This question has multiple parts: a. Run a Pearson correlation for the above data and include the correlation table from SPSS below. b. Interpret the results (interpret these data using the general range of very weak to very strong)
