Scenario 7

Code Solution

The solution listed below is one example of a program that could be used to accomplish each task within the scenario. Your code can be different, as long as it results in the same answers. 
data work.scenario7;              /*#1*/
   set cert.temp18;               /*#2*/
   format Day date9.;             /*#3*/
   Month=month(day);              /*#4*/
run;
proc freq data=work.scenario7;    /*#5*/
   tables HighTemp;               /*#6*/
run;
proc means data=work.scenario7;   /*#7*/
   class month;                   /*#8*/
   var AvgLowTemp AvgHighTemp;    /*#9*/
run;
1 The DATA step creates a new temporary data set named Work.Scenario7.
2 The SET statement is used to read observations from one or more SAS data sets.
3 The FORMAT statement formats the Day variable in the date9. format.
4 The MONTH function returns the numeric value of the month within the Day variable.
5 The FREQ procedure creates one-way, two-way, and n-way tables. It also describes data by reporting the distribution of variable values.
6 The TABLES statement requests one-way to n-way frequency and crosstabulation tables and statistics. In this case, that is a one-way frequency with the default statistics for the variable HighTemp.
7 The MEANS procedure is used to compute descriptive statistics for the variables stated in the VAR statement.
8 The CLASS statement provides separate calculations for each value of the Month variable.
9 The VAR statement identifies the two variables, AvgLowTemp and AvgHighTemp, as the analysis variables, and also controls their order in the output.
Output A2.9 PROC FREQ Results of High Temp
PROC FREQ Results of High Temp
Output A2.10 PROC MEANS Results
PROC MEANS Results
