PROC FREQ DATA = mydata; TABLES var 1 *var2/OUT = outtab analysis; RUN; O c. PROC FREQ DATA = mydata OUT = outtab.analysis; TABLES var1 *var2; RUN; O d. PROC FREQ DATA = mydata OUT = analysis.outtab; TABLES var 1 *var2; RUN; O e. PROC FREQ DATA = mydata; TABLES var1 *var2/OUT = analysis.outtab; Which sample statistics measure the spread of a numeric variable's distribution? Select one or more: 0 a. JOR. O b. Mean O c. Standard Deviation d. Median O e. Variance Consider the roughly symmetric histogram below. What do we know about the relationship between the mean and median? 350 300 250 200 Frequency 150 100 50 0 6.30 7.35 8.40 9.45 10.50 11.55 12.60 Select one: a. The mean is approximately equal to the median. O b. There isn't enough information to know the relationship between the mean and median. O c. The mean is greater than the median. O d. The mean is less than the median. Which code below correctly creates a scatter plot with regression line for the MPG_Highway and MPG_City variables from the sashelp.cars dataset where the color and marker used for the points have been changed? (Recall the useful help page linked here. E) Select one: O a. PROC SGPLOT DATA = sashelp.cars MARKERATTRS=(color=lightgreen symbol=trianglefilled); REG X = MPG_Highway y = MPG_City; RUN; O b. PROC SGPLOT DATA = sashelp.cars; REG x = MPG_Highway y = MPG_City/MARKERATTRS (color=lightgreen symbol=trianglefilled); RUN; O c. PROC SGPLOT DATA = sashelp.cars; REG x = MPG_Highway y = MPG_City/MARKERATTRS=(color=lightgreen symbol=trianglefilled); RUN; O d. PROC SGPLOT DATA = sashelp.cars/MARKERATTRS=(color=lightgreen symbol=trianglefilled); REG X = MPG_Highway y = MPG_City; RUN; O e. PROC SGPLOT DATA = sashelp.cars; REG X = MPG_Highway y = MPG_City MARKERATTRS=(color=lightgreen symbol=trianglefilled); RUN; What is an interpretation of the IQR = 03-01? Select one: a. The range (spread) of the middle 50% of the data. O b. The IQR divided by 2 gives the median. c. The IQR is another way of looking at the median. O d. The location of the middle of the data.
