The box-and-whisker plots show a sample of 40 boys and 40 girls and their heights in inches. Select all the true statements. Вoys Girls 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 Height in Inches O The median value is greater for the girls. O The interquartile range of both sets is 7 inches. O Seventy-five percent of the girls are 58 inches or taller. O Seventy-five percent of the boys are 59 inches or taller. O The boys and girls have the same minimum and maximum value.
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.
