Document Summary

Statistics is a set of rules and procedures used to summarize and. Descriptive stats: summarizing the observations we make, summarize the results, avg. , frequency distribution, standard deviation (sd), range. Inferential stats generalize to people in general, mostly based on probability. Scientific method use a specific technic to finding things out, a way of finding things out and involves two kinds of logics. Deductive logic: go from a general statement or assumption to specific. General theory: idea of how cause and effect works generate a prediction about a specific situation. Objective observation everyone sees the same thing. Observe samples make conclusions about the population, need inferential stats for it. Explain why the observed relationship between variables occurs. Variables is an attribute that takes on different values ex. Hair colour (variable name); brown, red, blonde, black(level) qualitative variable. Age (variable name) quantitative variable because it has numbers. Constant attribute with only one level.
