7. Slide 2- 7 What Are Data? Data can be numbers, record names, or other labels. Not all data represented by numbers are numerical data (e.g., 1=male, 2=female). Data are useless without their context…

8. Slide 2- 8 The “W’s” To provide context we need the W’s Who What (and in what units) When Where Why (if possible) and How of the data. Note: the answers to “who” and “what” are essential.

9. The characteristics recorded about each individual are called VARIABLES (HINT: this is the WHAT of the W’s)

10. CATEGORICAL VARIABLES When a variable names categories and answers questions about how cases fall into these categories we call is a CATEGORICAL VARIABLE

11. QUANTITATIVE or NUMERICAL VARIABLE When a measured variable with units answers questions about the quantity of what is measured we call it a QUANTITATIVE or NUMERICAL VARIABLE
