Hello,
I need help with the following statistical lab. More specifically how to enter the data in the online calculator and how to interpret it as well as answer the questions in bold below. Thank you in advance for your help!
SAT Training
A psychologist developed a training program to enhance performance on the math portion of the SAT exam. She obtained a practice copy of the exam to use in assessing whether the training was effective in boosting students' SATmath scores. Questions were randomized to control for the test-retest practice effect.
Fifteen students participated in the study. Participants took the math exam then completed the experimental training over the course of several weeks prior to taking the math exam the second time. Scores are reported in the table below:
At a significance level of .05 can it be concluded that the training resulted in higher scores?
Participant | Score 1 | Score 2 |
---|---|---|
1 | 224 | 226 |
2 | 217 | 224 |
3 | 232 | 231 |
4 | 214 | 217 |
5 | 216 | 217 |
6 | 222 | 225 |
7 | 226 | 225 |
8 | 219 | 224 |
9 | 219 | 222 |
10 | 222 | 223 |
11 | 221 | 226 |
12 | 225 | 228 |
13 | 216 | 219 |
14 | 224 | 223 |
15 | 218 | 222 |
Use a computer program such as Excel or an online calculator to conduct the statistical test at alpha .05 using the t-statistic with the p-value approach.
There is an online descriptive statistics calculator free for use. It will return the sample mean, variance and standard deviation.
There is an online dependent samples t-test calculator and a Guide to Reporting t-Test Results in APA Style also free for use.
Please answer the following:
State the hypotheses and summarize the results and conclusions:
State the hypotheses in complete statements and statistical symbols.
Report the value of the t-statistic and degrees of freedom and whether a one- or two-tailed test was used.
Report the p-value of the test statistic.
Report whether the result is statistically significant.
State the conclusion in APA style.
Paste in a copy or screenshot of the calculator output(s).
