A teacher categorized students by whether they regularly completed their homework (or not) and whether they passed the course (or not). The data are in the table below. Complete the Venn Diagram by using the table of values provided. Then answer the additional questions below. Completed Homework Did not Complete Homework Total Passed the Course 24 5 29 Did not Pass the Course 6 15 21 Total 30 20 50 Completed Homework Passed the Course U Enter all of your results as percents rounded to two decimal places. What percent of all the students passed the course and completed homework? % What percent of all the students passed the course and didn't complete homework? % What percent of students who completed homework passed the course? % What percent of students who did not pass the course did not complete the homework?
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.
