Children of three ages are asked to indicate their preference for three photographs of
adults. Do the data suggest that there is a significant relationship between age and
photograph preference? What is wrong with this study? [Chi-Square = 29.6, with 4
df: ? < 0.05].

###		Photograph
Age of child		A	B	C
	5-6 years	18	22	20
	7-8 years	2	28	40
	9-10 years	20	10	40

Chi-Square test of independence:

Since p-value < 0.05 i.e. we can reject H₀ and hence it can be concluded that there is a significant relationship between age and photograph preference.
