The following tables list the ages of female and male actors when they starred in their Oscar-winning Best Actor performances. Construct a back-to-back stem-and-leaf plot for the following data. Ages of Best Female Actor Award Recipients, Academy Awards, 1975-2010 42 21 26 41 41 25 36 26 33 32 80 35 41 42 35 33 29 28 31 33 30 74 36 29 33 45 61 49 49 32 38 39 33 61 34 45 Ages of Best Male Actor Award Recipients, Academy Awards, 1975–2010 56 62 46 38 43 40 60 51 36 30 32 47 40 42 29 42 54 43 37 52 37 76 37 38 39 38 45 50 45 48 36 60 60 53 32 45
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.
