Sexual assault in college: In a Washington Post/Kaiser Family Foundation poll conducted from January through March 2015, 46% of adults (ages 17‑26) who attended college during the past 4 years say it’s unclear whether sexual activity when both people have not given explicit agreement is sexual assault. The survey methodology section states that the margin of error is ±3.5% at the 95% confidence level.


What does this margin of error tell you about the results of this poll?




  1.  We are 95% confident that the sample proportion is off by 3.5%.

  2.  We are confident that 95% of the responses are within 3.5% of the population proportion.

  3.  We are 95% confident that the population proportion is within 3.5% of the sample proportion of 46%.
