1. Fill in the blanks to summarize what the descriptive statistics tell us about application entry times. Select from the options to the right of each blank. Based on the evidence from the data, the average time required to enter admissions data was (7.85 / 7.40), but the relatively large standard deviation suggests that (few / many) observations differ substantially from the (mean / median). The (mean / median) tells us that half of the applications required less than .(7.40 / 7.85) minutes to enter. The fact that the (mean / median) exceeds the (mean / median) suggests that some unusually (small / large) values in the (sample / population) affected the value of the mean. 2. Write an interpretive conclusion about application entry times based on the histogram graph. Start with "Based on the evidence from the histogram..."
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.
