Data Analysis

Type : SASHELP

Both DATA steps use the standard `sashelp.cars` dataset as the input source, which is an example dataset provided with SAS.

1 Code Block

DATA STEP Data

Explanation :
This DATA block creates a new dataset named `cars2` from `sashelp.cars`. It evaluates the `MSRP` value to assign a numerical `Cost_Group` (1, 2, 3, or 4) using a series of `IF-THEN/ELSE IF-THEN/ELSE` conditions. Only the variables specified in the `KEEP` statement are retained in the final dataset.

Copied!

1	DATA cars2;
2	SET sashelp.cars;
3	IF MSRP<20000 THEN Cost_Group=1;
4	ELSE IF MSRP<40000 THEN Cost_Group=2;
5	ELSE IF MSRP<60000 THEN Cost_Group=3;
6	ELSE Cost_Group=4;
7	keep Make Model Type MSRP Cost_Group;
8	RUN;

2 Code Block

DATA STEP Data

Explanation :
This DATA block replaces the previously created `cars2` dataset. It first defines the length of the new character variable `CarType` to 6. Then, it assigns the value 'Basic' to `CarType` if `MSRP` is less than 60000, and 'Luxury' in all other cases. The 'Make', 'Model', 'MSRP', and the new `CarType` variables are retained.

1	DATA cars2;
2	SET sashelp.cars;
3	LENGTH CarType $ 6;
4	IF MSRP<60000 THEN CarType="Basic";
5	ELSE CarType="Luxury";
6	keep Make Model MSRP CarType;
7	RUN;
