Welcome to the Stat Rescue! If you are here, you are probably in a stats class and looking for some extra help. These are my reflections on how to make learning statistics easier. Almost everyone can learn statistics if it is presented to you in ways you are familiar with: Everyday English and examples are two big ways that I have found to make statistics much more accessible. Below is a list of topics I intend to cover. The ones that are hyper-linked have pages, and the ones that are not are forthcoming.
Understanding equations--A new languageMeasures of central tendency
Levels of measurement
Measures of variance
Frequency tables I
Frequency tables II
Association, strength and direction of relationships
Dependent vs. independent variable
Bivariate/two-way tables/Crosstabs
Distribution: Normal, standard normal, skewness, kurtosis
Sampling distribution
Degrees of freedom
Z scores: for observations in a sample
Confidence intervals
Z scores: for sample means in a theoretical distribution
Standard error vs. standard deviation
Hypothesis testing: General
Hypothesis testing: One mean, two mean and one tail, two tail
Measures of association: Lambda, gamma
Elaboration analysis
