For each of the following variables enter as many of the below descriptions (labelled A thru H) that describe the type of data that is being measured. Although there are 3 blanks available to describe each variable, only insert those letters that apply. If you answer A or B for a particular variable, you don’t need to answer with any other variable. nominal ordinal interval ratio discrete continuous cross-sectional time series _____ _____ _____ the number of aunts and uncles that each of a random sample of 50 students have _____ _____ _____ the temperature (to the nearest degree) that food experts believe a rare steak should be cooked to _____ _____ _____ the school colours of Windsor high schools _____ _____ _____ the exact distance, in kms, a marathon runner ran each of the last 30 days preparing for her next marathon _____ _____ _____ the preferred temperature for sleeping by Canadians (cold, cool, warm, hot) _____ _____ _____ the numbers that banks assign to Canadians’ savings accounts
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.
