The table shows the length, in km, of an Uber ride in New York City and the corresponc price, in USD, of the ride. Length in km (2) 5 8 10 13 16 20 25 Price in USD (y) 6.25 12.0 15.5 21.0 25.5 31.5 37.0 46.5 (a) Draw a scatter diagram for the above data on the axes below. Use a scale of 1 unit represent 2 km on the r-axis and 1 unit to represent 5 USD on the y-axis.
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.
