The 10% condition states that sample sizes should be no more than 10% of the population. Whenever samples are involved in statistics, check the condition to ensure you have sound results. Some statisticians argue that a 5% condition is better than 10% if you want to use a standard normal model. For example, the 10% condition normally applies ...Normality (Large Counts Condition) ... 🎥 Watch: AP Stats - Sampling Distributions for Means.

The mean of the sampling distribution is always equal to the population proportion (p), and the standard deviation is calculated as sqrt (p (1 − p) / n), where n is the sample size. These measures are useful for understanding the distribution's center and spread, respectively, regardless of its shape.To meet the condition of Large counts for any X^2 Statistic.

It can be used when the samples are independent, n1ˆp1 ≥ 10, n1ˆq1 ≥ 10, n2ˆp2 ≥ 10, and n2ˆq2 ≥ 10.
