A researcher is interested in understanding the smartphone habits of college students in the US. To answer this question, the researcher conducts an online survey of 1000 randomly selected college students from California. 77% of these students reported using their smartphones as soon as they wake up in the morning. The randomly selected college students from California are an example of a _________.

[example continued…] If the following scores are population data, [7,4,8,3,3] the Population Variance equals

What is the appropriate measure of central tendency for scores measured on a nominal scale?

[Example continued…] The personality trait of “Conscientiousness” (someone who is organized, responsible, and can control their impulses) has μ = 120 and σ =9. Test whether ARC students (n = 9, M = 126) differ on Conscientiousness. α = .05. Do ARC students differ on “Conscientiousness”?
