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…

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.

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

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

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

SCHOOLS: The State Education Department requires local school districts to keep these records on all students: age, race or ethnicity, days absent, current grade level, standardized test scores in reading and mathematics, and any disabilities or special education needs the student may have. Let’s identify the W’s, name the variables and classify them as categorical or quantitative. Here we go……………………
