The data set below provides the monthly rent (in dollars) paid by 7 tenants. 990,879,940,1010,950,920,1430 Suppose the rent for one of the tenant's changes from $1430 to $1115. What is the mean before the rent change? What is the mean after the change?
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.
The data set below provides the monthly rent (in dollars) paid by 7 tenants.
990,879,940,1010,950,920,1430
Suppose the rent for one of the tenant's changes from $1430 to $1115.
What is the mean before the rent change?
What is the mean after the change?
The monthly rent (in dollars) paid by 7 tenants are,
990, 879, 940, 1010, 950, 920 and 1430.
The rent for one of the tenant's changes from $1430 to $1115.
