A group of students wanted to determine if three compost types (kitchen, vermi, commercial) have an effect on the height of radish seedlings. The results are shown in the table. What is an appropriate introductory/context statement for the APA report?
A linear regression analysis was conducted in order to examine if there is a significant difference in the height of radish seedlings treated with kitchen vs. commercial compost.
An independent t-test was conducted in order to examine if there is a significant difference in the height of radish seedlings treated with three different compost types.
A one-way analysis of variance was conducted in order to examine if there is a significant difference in the height of radish seedlings treated with kitchen vs. commercial compost.
A one-way analysis of variance was conducted in order to examine if there is a significant difference in the height of radish seedlings treated with three different compost types.
A group of students wanted to determine if three compost types (kitchen, vermi, commercial) have an effect on the height of radish seedlings. The results are shown in the table. What is an appropriate APA report?
Analysis of results shows that there is no significant difference in the heights of radish seedlings, F(2, 27) = 3.3541, p < .001.
Analysis of results shows that there is no significant difference in the heights of radish seedlings, F(2, 27) = 189.5723, p < .001.
Analysis of results shows that there is a significant difference in the heights of radish seedlings, F(2, 27) = 189.5723, p < .001.

A group of students wanted to determine if three compost types (kitchen, vermi, commercial) have an effect on the height of radish seedlings. The results are shown in the table. What is an appropriate analysis of post hoc results?
Post hoc test results shows that radish seedlings treated with commercial compost (M = 16.09, SD = 0.26) have significantly lower height compared to radish treated with vermi (M = 14.95, SD = 0.30) and kitchen (M = 12.61, SD = 0.58) compost.
Post hoc test results shows that radish seedlings treated with commercial compost (M = 16.09, SD = 0.26) have significantly greater height compared to radish treated with vermi (M = 14.95, SD = 0.30) and kitchen (M = 12.61, SD = 0.58) compost.
Post hoc test results shows that radish seedlings treated with kitchen compost (M = 16.09, SD = 0.26) have significantly greater height compared to radish treated with vermi (M = 14.95, SD = 0.30) and commercial (M = 12.61, SD = 0.58) compost.
Post hoc test results shows that radish seedlings treated with vermicompost (M = 16.09, SD = 0.26) have significantly greater height compared to radish treated with commercial (M = 14.95, SD = 0.30) and kitchen (M = 12.61, SD = 0.58) compost.
A group of students wanted to determine if three compost types (kitchen, vermi, commercial) have an effect on the height of radish seedlings. The results are shown in the table. What is a likely conclusion?
This study recommends using fertilizer, not compost, for radish plants.
The results imply that kitchen compost is the best among all compost types.
The results imply that all compost types lead to equal growth among radish plants.
The results imply that commercial compost leads to significantly better growth in radish than vermi and kitchen compost.
