To create the variable STRLEADINDEX using the ANES dataset, we will combine the variables STRLEAD1 and STRLEAD2. The new variable will represent the index of support for a strong leader, with zero signifying a lack of support for a strong leader. The process to create the variable STRLEADINDEX involves combining the values of STRLEAD1 and STRLEAD2. Since zero signifies a lack of support for a strong leader, we will sum the values of STRLEAD1 and STRLEAD2 and then subtract one from the sum to obtain the final index
