Question

Answer the ff questions:

a. Report the results using APA format (see Chapter 12-14 modules for reference)
• Ensure that you include in your results the following: (1) the statistical test used,
(2) the descriptive statistics, specifically M and SD of the samples/treatment
conditions/groups, (3) conclusion/s, (4) test statistic/s, (5) degrees of freedom/s,
(6) probability/ies of committing a Type I error, and (7) effect size/s.
• Provide the results of the post hoc test/s and simple effects analyses if
necessary.
• Ensure that the means, SDs, and required statistics are rounded off to two or
three decimal places.
• Use a zero before the decimal point in numbers that are less than 1 when the
statistic can exceed 1, but do not use a zero before a decimal fraction when
the statistic cannot be greater than 1.
• Show how you got the test statistic/s and the effect size/s.
b. There is still some sort of debate if hot, warm, or cold water is effective in removing
germs from clothing. Based on the results obtained, which temperature is the most
effective? (Provide evidence to your answer by using the results from the post hoc
test/s and/or simple effects analyses)

Transcribed Image Text:Because of their concerns with the COVID-19 pandemic, your parents, who looked frantic, told you to do laundry regularly to help kill the said virus. As it is probably your first time to do laundry, you want to determine whether the brand of laundry detergent used and the temperature affects the amount of dirt removed from your laundry. You bought in your local supermarket two different brands of detergent (i.e., Sealy and Super Fisher) and chose three different temperature levels (i.e., cold, warm, and hot). You then divided your laundry into 24 piles of equal size and assigned each 4 piles into the combination of brand of detergent and temperature. The data for the amount of dirt removed in pounds are found below (alpha at .05; apply Tukey's HSD if necessary): Sealy Super Fisher Cold 4 5 6 5 M = 5.00 SD = 0.82 6 6 4 4 M = 5.00 SD = 1.15 M = 5.00 SD = 0.93 ANOVA Summary Table: SOURCE Between treatments Detergent Temperature Interaction Within treatments Total Warm 7 9 M = 9.00 SD = 2.16 8 12 M = 13.00 SD = 1.41 SS 236.83 20.17 200.33 13 15 12 12 M = 11.00 SD = 2.73 16.33 37.00 273.83 df 5 1 2 2 18 F M = 10.50 SD = 1.29 MS Hot 10 12 M = 12.00 SD = 1.41 ?? ?? 11 9 M = 11.25 SD = 1.49 ?? ?? 12 13 10 13 M = 8.17 SD = 2.79 M = 10.00 SD = 3.91 F(??, ??) = ??
