Give 5 weaknesses of longitudinal studies. | 1) Can be expensive and time consuming due to extended period of time 2) Difficult to replicate due to time constraints and opinions and influences changing over time 3) Factors changing for the individuals in the study may decrease cause and effect 4) High drop out rate and those who don’t drop out may leave bias sample due to having something in common 5) Published research could be outdated due to time passing |
