State whether the data described below are discrete or continuous, and explain why. The total numbers of flights by different airlines between two specific cities in the past month Choose the correct answer below. O A. The data are discrete because the data can take on any value in an interval. O B. The data are discrete because the data can only take on specific values. O C. The data are continuous because the data can only take on specific values. O D. The data are continuous because the data can take on any value in an interval.
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.
