A Chi-Square Test of Independence was conducted to determine whether there was an association between nationality and scholarship awarded.
The results showed that there was a statistically significant association between the two variables, χ²(1) = 81.30, p < .001.
The strength of the association was strong, as indicated by Cramér’s V = 0.53.
