In your own words explain the difference between "descriptive statistics" and "inferential statistics." Do not just give definitions.
# In your own words, define the four different sampling techniques.
# Develop your own hypothesis about a situation of interest, for example: "Middle income families containing four members spend 10% of their gross income on clothing per year."
# Select one of the four sampling techniques and give a detailed design of how you would gather sampling data to answer your hypothesis.
# Select a second sampling technique for the same hypothesis and give a second detailed design of how you would gather sampling data.
