= data analysis and experimental thinking =
|
|
some boring statistics stuff:
|
|
* uni/bi/multi variate data
|
|
* types of data: nominal, numerical, etc
|
|
* populations vs samples
|
|
* parameter vs statistic
|
|
* summary statistics: mean, mode, etc
|
|
* using tables, plots to explain data, and how it can be misleading
|
|
|
|
important questions when understanding the distribution of numerical data:
|
|
* what is the range of the data
|
|
* what is the central tendency
|
|
* how spread out are the values
|
|
|
|
central tendency = most common: mean, median, mode
|
|
variability = a single value to measure internal variation of data; range, variation, standard deviation
|
|
other stats = five number summary
|
|
|
|
now we talk about different graphs
|
|
* histogram
|
|
* density plot
|
|
* box plot
|
|
|
|
bivariate data
|
|
* contingency tables = tables with 2 variables
|
|
* t-test
