SampDist2Means function

Distribution of the Difference of Sample Means

An app to explore the Central Limit Theorem in the context of the difference of sample means.

SampDist2Means(pop,max.samp.sizes=50,sim.reps=1000)

Arguments

• pop: A data frame representing the population from which samples are taken.
• max.samp.sizes: Largest sample sizes shown on the sliders.
• sim.reps: Number of simulation repetitions to construct empirical distribution of difference of sample means.

Returns

Graphical and numerical output.

Note

Uses manipulate in R Studio. Also requires package lattice.

Examples

## Not run:

data(imagpop)
if (require(manipulate)) SampDist2Means(imagpop)
## End(Not run)
