Week4 Assignment Total: 25 pts 1. What are the two conceptual strategies for data classification? (3pts) 2. The following table shows the State-level Percentage of People in Poverty Using 3-Year Averages (2015 - 2017). Data is ranked from the lowest to highest. N = 51. Classify the data using three methods: 1) equal interval based on range; 2) equal interval not based on range; and 3) quantile. Write down the frequency table for each of the three methods.
