十月即將過半,快來接收期中複習第二彈
本周專題為統計學
Chapter 01:EXPLORING Univariate data
There are two types of variables: qualitative/categorical and quantitative.
1.2 SUMMARIZING DISTRIBUTIONS
The empirical rule (also called the 68-95-99.7 rule) applies specifically to symmetric bell-shaped data (not to skewed data!). in this case, about 68% of the values lie within 1 standard deviation of the mean, about 95% of the values lie with 2 standard deviation of the mean, and more than 99% of the values lie within 3 standard deviations of the mean.
Chapter 02:Exploring Bivariate data
2.1 SCATTERPLOT AND CORRELATION
If there is no association between the two classification criteria, then the expected number of measurements in a given cell of the contingency table is equal to:
Expected cell count > observed cell count, which means there is negative association between being female and majoring in science.
Expected cell count < observed cell count, which means there is positive association between being male and majoring in science.
