US Women under 40: General demographic notes, con. • When running ANOVA analyzing differences between those who have visited a Hollaback! site and those who haven't, we found significant differences on ALL types of harassment, age at harassment, and comfort talking about harassment – We cannot tell if these experiences led them to Hollaback!, or if being ac/ve in Hollaback! made them more sensi/ve to observing such experiences.
• What can we then generalize to?
– This was not a random sample, so we can say that, among female respondents under 40 from the US, we found XYZ. Respondents were not randomly selected, so extrapola/on to percentages in the general popula/on should be avoided or only carefully applied.
