What typical form does an F statistic take? a. a ratio with mean difference on the numerator and standard error on the denominator b. a ratio with sum of the squared deviations between groups (or treatments) on the numerator and sum of the squared deviations within groups (or error) on the denominator c. a ratio with variance between groups (or treatments) on the numerator and variance within groups (or error) on the denominator d. a ratio with sum of the products of deviations on the numerator and the square root of the product of sum of squared deviations on the denominator
Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.
