An area. A probability.
Small steps.
Lasting understanding.
Make yourself curious
Start with an idea.
Three interactive lessons.
Plenty of room to experiment.
The normal distribution
Move a cutoff. See how the area under a curve becomes a probability.
Confidence intervals: z
Connect sample size and confidence with the precision of an estimate.
Confidence intervals: t
Explore the extra uncertainty when the population spread is unknown.

The learning path
A little structure.
A lot to discover.
A focused path through statistics,
organized into 12 manageable modules.
Four lessons are available across modules 01, 04, and 06: sampling methods plus three interactives. The remaining modules are a proposed course outline.
The StatsCove approach
Understanding starts
with “what if?”
What if the sample were larger? What if the data were more spread out? What if we wanted to be more confident?
StatsCove gives those questions a place to go. Each lesson brings a statistical idea, an interactive visual, and a little room to experiment together.
