a)This is a within group design , which is sometimes called a repeated measures design. This type of experimental design is when one set of participants are tested more than once and their scores are compared. It is called 'repeated measures' because the researchers are repeatedly measuring the responses received in terms of frequency , timing ,amount of information provided about the department , emotional warmth and enthusiasm toward the students.
b) Independent variables are the type of parties. There are two level first is conservative and second is liberal.
c) Dependent variable:
1) frequency (quantitative variable)
2) timing ( quantitative varibale)
3) amount of information( qualitative variable)
4) emotional warmth (qualitative variable)
5) enthusiam toward student (qualitative varible)
d) It would have been possible to conduct paired design because the samples were paired, here the observations are paired that is the pair of observations (xi,yi) , (i=1,2...,n) corresponds to the same(ith ) sample unit.
