Dr. Croft should be most concerned with the history effect. The economic change could have had a significant impact on the variables that she was studying, and it could have affected the relationships between the variables. This could threaten the internal validity of her study. Dr. Croft needs to take into account the potential confounding effects of the economic change to draw accurate conclusions from her data.
