For a chi-square test, the _______ are data that is ______.

Observed frequencies ; obtained from independent variables

Observed frequencies ; obtained from a normal distribution

Expected frequencies ; predicted by H0

Expected frequencies ; selected from the sample

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.
