Sample Proportion Simulation (PSIMUL)

Population Proportion
This is the proportion of the population that demonstrates a particular characteristic. Enter as decimals (i.e. 50% = 0.5). Please use keyboard to enter numbers with more than two significant digits.

Sample Size
This is the size of the simulated sample. For each member of the sample, a random number will be generated between 0 and 1. If that random number is less than or equal to the population proportion, then that member will be considered to have the population characteristic (i.e counted as a “success”).

Number of Simulations
This is the number of samples that will be simulated. For each simulation, the sample proportion will be calculated as the number of successes divided by the sample size.

Decimal Accuracy
This will not affect calculations in any way. Sample proportions will be reported to this number of digits after rounding. Two decimal places is typical. The distribution of sample proportions can be easily plotted in a dot plot or histogram.

WHY. We are a small, independent publisher founded by a math teacher and his wife. We believe in the value we bring to teachers and schools, and we want to keep doing it.

DISPUTES. If we have a dispute that we cannot resolve on our own, we will use mediation before filing a lawsuit in a regular court (except that we can use small claims court). Mediation means we will each present our case to one or more professional mediators who are chosen and paid by all parties to the dispute, and the mediator(s) will work with us to find a fair resolution of our dispute. Mediation is a faster and less formal way of resolving disputes and therefore tends to cost less.

If you have a dispute, please send a letter requesting dispute resolution and describing your claim to:
