A survey of 60 students at a campus on the preference of Red Curry and Green Curry was carried out. The results show 38 liked Red Curry and 45 like Green Curry. 1) How is it possible when the numbers 38+45=83 is more than 60? 2) Represent these data in a Venn diagram 3) Write a set equation to explain this finding using R to represent students who like Red Curry and G for students who like Green Curry
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.
