Which ONE of the following equations forms the basis of the One-way Anova calculations? between-groups sum of squares plus within-groups sum of squares = total sum of squares between-groups sum of squares divided by within-groups sum of squares = total sum of squares within-groups sum of squares divided by between-groups sum of squares = F-statistic between-groups sum of squares plus within-groups sum of squares = F-statistic
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.
Below is some info about a certain One-way Anova F-test. Identify the null hypothesis, alternative hypothesis and final conclusion by choosing the BEST option for each blank.
Categorical Variable: type of meat being cooked (all pieces of meat are cut into one-inch cubes)
Quantitative Variable: time required to bring internal temperature to 165 deg F, when cooked at 350 deg F
