Record the type of screened electronic devices (ipad, iphone, TV, laptop, etc) you have in your home AND their screen sizes. Screen size is measure across the diagonal. What type of statistical measures?
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.

What type of statistical measures?
The data measured in the experiment are of four types, they are nominal, ordinal, interval and ratio.
Nominal - It is a type of categorical data which are named not ordered
Ordinal - It is a type of categorical data which are ordered
Interval - It is a numerical and contains values in a range
Ratio - It is a numerical and which contains absolute value, ordered and contains value in an range
