Name two files required for merging . what does each of thes files contain?​

Answer 1

$\huge\underline\mathfrak\pink{♡Answer♡}$

The most common form of merging is what SPSS calls a parallel "matched merge", where two files are sequentially organized and combined to create one large file. To complete this process, each file must contain the same shared unique identification variable; this is used to sort on and then to merge on.
