# A Chi-Square Test of Independence was conducted to determine if there was an association between student nationality (domestic versus international) and whether or not they have a scholarship (yes versus no).

# The results showed that there [was] an association between the two variables, χ²(1) = 81.297, p < .001.

# The association was [strong], (Cramer's V = .53).
