For Assignment 5 in our course, the researchers hypothetically tested two groups of participants. The independent variable was location of exercise with two levels "in the lab" and " in nature". The dependent variable was scores on a test of anxiety levels. Using the information provided below, calculate variance for each of the groups and F-max. Should the researchers run this study? Explain why or why not. SS (lab exercise) = 600, n = 7 SS (exercise in nature) = 1910, n = 7
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.
