Document Summary
Conducting studies to collect, summarize, analyze and draw conclusions from data. Descriptive statistics: organization, summarization and presentation of data: taking data and presenting it through graphs, etc. Inferential statistics: generalization from samples to populations, estimation, hypothesis testing and prediction making: take sample and try to say something about the population it comes from. Quantitative: count or measure of something. Order: everyone would see the same order. Temperature is example: ratio: 0 means none of what you are measuring natural starting point means absence. Temperature: 0 does not mean no energy or heat in the system. Not a natural starting point because 0 is not absence. If saying this is 5x bigger or 10x bigger, 0 has to be the natural starting point. Does it mean there is nothing there? (if nothing there, then ratio data) )q of (cid:882) doesn"t mean there is no intelligence. When you see a number, that"s what it means.
