A hasty generalization is a conclusion based on a small sample size, rather than looking at statistics that are much more in line with the typical or average situation.
A sample of hasty generalization is when FDR says in his speech that the attack yesterday on the Hawaiian Islands has caused severe damage to American naval and military forces. I regret to tell you that very many American lives have been lost. FDR based this conclusion on what probably was told but not even the military at Pearl Harbor knew the exact numbers of deceased but several day later.
Middle class women were expected to hire fewer servants and do more of the household chores themselves. Working and earning money was not allowed in most businesses so they had to work more in the house. This wasn't a problem for wealthy people because they would always stay wealthy, or the poor because they never had servants to begin with.
