10. Sampling Distributions

Central Limit Theorem: If the sample size ($n$) is large enough (usually $n \ge 30$), the sampling distribution of the sample mean will be approximately normal, regardless of the population distribution.
Standard Error: The standard deviation of the sampling distribution ($\frac\sigma\sqrtn$).

How to Use This Resource Effectively (For Students)

Simply possessing the An Introduction to Statistics and Probability by Nurul Islam PDF is not enough. You need a strategy. I recommend the following legitimate sources:

4. Measures of Dispersion (Variability)

These describe how "spread out" the data is.

Range: Difference between the maximum and minimum values ($Max - Min$).
Variance ($s^2$ or $\sigma^2$): The average of the squared differences from the Mean.
- Sample Formula: $s^2 = \frac\sum(x - \barx)^2n-1$.
Standard Deviation ($s$ or $\sigma$): The square root of the variance. It is in the same units as the original data.
Coefficient of Variation (CV): The standard deviation expressed as a percentage of the mean. Useful for comparing variability between two different datasets.
