The lecture Standardizing Data and the Normal Distribution Part 1 by David Spade, PhD is from the course Statistics Part 1. It contains the following chapters:
In terms of data, what does it mean to shift a data set?
Why do we standardize data?
What does the empirical rule tell us?
Which of the following describes an appropriate and correct use of the ztable?
How can we assess whether our data are roughly normally distributed?
Suppose the mean STAT score is 80 and the standard deviation is 10. What is the zscore for a STAT score of 75?
Suppose the mean of a, b, c is 50. What would be the mean of (a+10), (b+10), (c+10)?
Suppose the mean of a, b, c is 50. What would be the mean of (a10), (b10), (c10)?
Suppose the standard deviation of a, b, c is 5. What would be the standard deviation of (a+10), (b+10), (c+10)?
Suppose the mean of a, b, c is 50. What would be the mean of (10a), (10b), (10c)?
