Large flow chart of hypothesis tests, includes null & alternative hypotheses, regular & non-parametric tests
Streamlined flow chart of hypothesis tests common in Biology IAs
1 Categorical explanatory variable (1 treatment) , quantitative, continuous response variable
Each subject gets 2 treatments , quantitative, Continuous response variable
2 treatments (qualitative explanatory variables) tested with quantitative continuous response
1 Categorical explanatory variable, response is categorical
1 population, 2 Categorical explanatory variable, responses are categorical
2 populations, 1 categorical explanatory variable, responses are categorical
>2 treatments (qualitative explanatory variables) tested with quantitative continuous response variable
(for repeated measures eliminate Independence condition & use the 1-way ANOVA Repeated Measures calculator)
>2 variables (each with multiple levels) tested with quantitative continuous response variable
Provides statistical test calculators and explanations, draws histograms & bar charts, slightly different terminology
Provides statistical test calculators and explanations, draws graphs, randomizes data, calculates binomial probability
Full Normal table for finding Critical Values, p-values, probabilities, and cut-offs
Full t-table for finding Critical Values, p-values, probabilities, and cut-offs
For more-precise p-values, use one of the online calculators or a TI84 / TInspire
For the Critical Value for a lower-tail test, add a negative sign to the value from the chart

For more-precise p-values, use one of the online calculators or a TI84 / TInspire
df = #categories-1 for a Goodness of Fit Test
df = (#rows-1)(#columns-1) for a test of Independence or Homogeneity
