12. In a recent survey, 200 randomly-selected high school students were asked whether they would prefer to win an Olympic gold medal, an Oscar, or a Nobel Prize. The results of their response and the sex of respondent are summarized in the table below. Olympic Medal Academy Award 10 Nobel Prize Female 41 43 94 Male 61 5 40 106 102 15 83 200 Draw a side-by-side bar chart to display the distribution of gender for each award the students would prefer to win for the 200 students.
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.
