Alternatively, a drawback to a longitudinal study is that it is time-consuming, costly, and age-related variations may be inaccurate. Moreover, member dropout, practice, and cohort outcomes may lead to the original sample no longer are representative of the population in which researchers would like to use. (Papalia, Feldman, and Martorell, 2014). Meanwhile, a cross-sectional design is more favorable economically; furthermore, it can indicate similarities and differences among age groups and minimizes the possibility of participant dropout and practice outcomes (Berk, 2014). As mentioned previously, a cross-sectional and longitudinal research has their strength and weakness; nevertheless, to overcome those faults a sequential design is required. The asset of this type of analysis is that we can compare both cross-sectional and longitudinal. Furthermore, it can show us the cohort effects as well as the age-related changes more competently than the longitudinal or cross-sectional design alone. Be that as it may, it can still be costly, and it will require a prolonged amount of time, determination, and a sophisticated analysis of the data (Berk,
