Question

Central Limit Theorem

a) When the population distribution is Normal. Predict: How do you think increasing the sample size for each sample selected from a Normal distribution will affect the shape of the sampling distribution of the means?

b) When the population distribution is uniform. Predict: How do you think increasing the sample size for each sample selected from a uniform distribution will affect the shape of the sampling distribution of the means?

c) When the population distribution is skewed. Predict: How do you think increasing the sample size for each sample selected from a skewed distribution will affect the shape of the sampling distribution of the means?

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
