We could do a survey to COLLECT data about something we want to study or investigate.What is statistics STATISTICS is the study of how to collect, organize, analyze, and interpret data.

We could do a survey to COLLECT data about something we want to study or investigate.

We could then ORGANIZE the data into a pie chart, t table, or graph.What is statistics STATISTICS is the study of how to collect, organize, analyze, and interpret data.

Going back to our Mt. Everest climbers, their age or height is QUANTITATIVE, male or female is QUALITATIVE.What is statistics POPULATION DATA the data are from EVERY individual of interest.What is statistics POPULATION DATA the data are from EVERY individual of interest.

SAMPLE DATA the data are from ONLY SOME of the individuals of interest.What is statistics POPULATION DATA the data are from EVERY individual of interest.
