A STARTING POINT, MADE FOR YOU
The survey researcher
toolbox.
Plan a simple sample and explore proportions and category counts.
INSIDE THE TOOLBOX
Starter collection8 useful places to start.
Sampling design, non-response, weighting and questionnaire quality need separate consideration.
Survey sample size estimate
Plan a sample for a proportion using a supplied margin of error.
Wilson proportion interval
Calculate a bounded confidence interval for a count out of a sample.
Contingency table chi-square test
Compare two categorical variables using an observed count table.
Chi-square goodness of fit
Compare observed category counts with expected relative weights.
CSV crosstab
Cross-tabulate categories with counts, sums or averages.
Filter CSV rows
Keep rows matching a literal text or numeric condition.
Descriptive statistics
Mean, median, mode, spread and standard deviation for your numbers.
Weighted average
Calculate an average with a different weight for each value.
