The students in Mr. Cooper's science class designed and flew paper airplanes. The 5 table shows the distance, in meters, that each airplane flew before landing on the ground. Based on this information, which statement is TRUE? Select all that apply. 12 9.5 10 8. 7.5 11 9. 7 21 10.5 8. 12 A The median is a better measure of center than the mean. B The mean is a better measure of center than the median. C The range is a better measure of variability than the IQR. D The IQR is a better measure of variability than the range. E The median is 9.75 feet.
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.
