Question Answered step-by-step Example t-test 1. Lucia is interested in the effect of presentation… Examplet-test1. Lucia is interested in the effect of presentation on children’s liking for vegetables; Lucia decides to examine the effect of single color vegetable combinations (e.g. carrots, beets and red peppers) vs. multiple color vegetable combinations (e.g. carrots, cauliflower and celery). She gives half the children in her preschool one kind of meal, and the other half the other kind of meal. Lucia finds the following results:GroupNMean % Vegetables EatenSDSingle Color1575%4Multiple Color1565%8 t = 2.15p = .033 Describe the mean differences between groups and results of the t-test as you would in the results section of a research paper. There was a statistically significant difference in the percent of vegetables eaten when children were given multiple colored vegetables compared to single color vegetables, t=2.15, p<.05. Children who were given multiple colored vegetables ate less on average (M=65%; SD=8) than children who were given single colored vegetables (M=75%; SD=4). Should Lucia reject the Null hypothesis? Why or why not? Social Science Sociology CAS 301 Share QuestionEmailCopy link Comments (0)
