1. The expected value of random variable is a measure of central location.
2. The variance of a random variable is a measure of variability.
3. Measures of variability give the degree of spread of the values.
4. The standard deviation is the square of the variance.
5. A standard normal distribution has a mean of 1 and a variance of 0.
6. The total area under the normal distribution curve is 1.
7. In a normal distribution, the mean, median, and the mode are equal.
8. The normal distribution is a distribution for continuous random variables.
9 The normal curve is symmetrical bell - shaped curve.
10. A sampling distribution is a probability distribution of a parameter.
11. Measures computed from sample data are called statistics.
12. Measures computed using population data are called parameters.
13. The mean of the sampling distribution of x is smaller than the mean of th
distribution of X.
