And then we're gonna think about how those parameters change as we do things to the data. If we were to shift the data up or down, or if we were to multiply all the points by some value, what does that do to the actual parameters? So the first parameter I'm gonna calculate is the mean. Then I'm gonna calculate the standard deviation. Then I wanna calculate the median. And then I wanna calculate, let's say the interquartile range. Inter, I'll call it IQR.
