(Lesson 7: Measures of Relative Standing or Position; 3-4) 3.30 LESSON 7: MEASURES OF RELATIVE STANDING OR POSITION (SECTION 3-4)How high or low is a data value relative to the others? We want standardized measures that will work for practically all populations involving quantitative data. PART A: zSCORESz=x±meanSDIdea: ²new mean=0²new SD=1³´µ¶·¸We are transforming the original data set of x-values into a new data set of z-values. x1x2x3etc.±±±z1z2z3etc.Subtracting off the mean from all of the original x-values recenters the data
