​Perform three post hoc tests, comparing the three pairs of means from the previous question. Are there significant differences between:

A. Baseline and one minute?

B. Baseline and two minutes?

C. One minute and two minutes?

Use a = .05 / 3 = .017 for each test.

i only need excel version no need for Spss. Thank you

In a study of embarrassment, Harris (2001) asked participants to sing the Star Spangled Banner in front of a video camera while she recorded their heart rate for two minutes. The following are data similar to the research results.
​Participant​Baseline​1 minute​2 minutes
​1​​​ 74​​ 88​​ 75
​2​​​ 76​​ 90​​ 77
​3​​​ 78​​ 89​​ 76
​4​​​ 76​​ 85​​ 76
Do the data show significant changes in heart rate over time?
Also, calculate the appropriate effect size for this test.
(Note: you do not need to show the calculations for SSError in Excel – you can just fill it in from SPSS.)

need help with only number5, can u do only excel of number5, i have done the spss part.

Solutions

Expert Solution

Step-1: perform one-way ANOVA

step-2: obtain least significant difference by using the given formula

LSD=t(α,error df)*sqrt(2*EMS/r)

Step-3: obtain the pairwise mean differences and compare with LSD

S stands for significant and NS stands for non-significant

Final Answer:

A. Baseline and one minute- Significant difference

B. Baseline and two minutes- Non significant difference

C. One minute and two minutes- Significant difference

For the previous problem, you should have found that there are significant differences among the three treatments. The primary reason for the significance is that the mean for treatment I is substantially smaller than the means for the other two treatments. To create the following data, we started with the values from problem 6 and added 3 points to each score in treatment I. Recall that adding a constant causes the mean to change but has no influence on the...

Introduction to T-tests Correlation looks for relationships between variables. T-tests compare means to look for differences between the means of two groups. STATISTICAL GUIDE:  The t-test is used to see if the difference between two means is statistically significant. There are multiple kinds of t-tests. In this exercise, we will focus on the t-test for independent groups (used to compare the mean scores of 2 different groups of participants in the same study) This t-test is used if the two means...
