# A Chi-Square Test of Independence was conducted to determine if there was an association between nationality and scholarship_awarded.

# The results showed that there [was / was not] an association between the two variables, χ²(1) = 81.297, p <0.001.

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