1) For each of the data sets below, indicate which type of graph you would choose to display the data and why you would choose that graph: a. Scores on an anxiety scale that range from “not anxious”, “somewhat anxious”, “moderately anxious” and “severely anxious”. b. Number of psychology majors versus other majors in your statistics course c. Mean speed (in seconds) to complete a set of puzzles – participants worked on either math puzzles or spatial navigation puzzles. 2) For each data set in the question above, list the variables present in the description and indicate if each variable is categorical or continuous
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.
