Probability Distributions
- standard deviation has a close relationship with the normal distribution or bell-shaped curve
- Aka sample distributions & distibution patterns
- distribution of all possible values that can be taken by that statistic.
- distribution of all possible values that can be taken by that statistic.
- formed by calculating that statistic for each of a large number of
samples of the same size that are drawn randomly from the population
- Normal distribution curve aka standard normal
distribution
- continuous and can display any value from a
dataset; it is a smooth, bell-shaped curve that is
symmetric about the mean of the distribution.
- symbol for the sample mean is .
- symbol for the sample mean is .
- defined by a formula in which there are only two sample variables
- mean and standard deviation (SD).
- mean and standard deviation (SD).
- continuous and can display any value from a
dataset; it is a smooth, bell-shaped curve that is
symmetric about the mean of the distribution.
- NORMAL DIS = PROB DIS so the area under the curve is equal to 1
- calculating probabilities using curve
- calculating probabilities using curve
