Question

Below are descriptions of some research studies. Each description contains sufficient information to determine the correct statistical test to use. Your task is 1) to determine which is the correct test, 2) to perform that test using our five-step hypothesis testing procedure, and 3) to make a decision about the null hypothesis using the results of the test. Choose your tests from these options: single-sample i test dependent-measures / test independent-measures t test Please report your answers in the following format: a. What is the name of the test to be performed? dependent-measures t test b. Hypotheses: _H: H, #4, H: 1, = H, c. What is the value of the test statistic for these data? t = 2.37 d. At a = .05 two-tailed, what is the statistical decision? reject H e. What is the effect size for this test? d=0.88 f. Write an APA style sentence that describes the outcome of this test: Dependent measures t test revealed that the participants remembered significantly more words using visual imagery (M = 22.72, SD = 2.88) than rote rehearsal (M = 18.92, SD = 1.97), t(22) = 2.37, p<.05 two-tailed, d = 0.88.

Answer 1

I am 2. Here ar instructed, answering the question to the point. : 1. Independent - measures t test. Because we are trying to figure to figure out for Statistically significant result between the means groups. 'Western' and 'Easterni. Here in two unrelated Ho: fw = NE 2. H₂: Mo & ME T stat; 3. For Calculating first We have calculate Mean and standard deviation of each sample X ORA 17.2 11 Xw 4.355 SE = 46.5 Sw 6.44 = q test; for pooled (11-1) sm +(12-)SE? sp = (mtn, -2) So t stat dof. = (9+9+2) = 16 GXW-TE)-(MN-ME 7 Sp 33. 1853 Sp V t + 1 h Where n = 9; 12=9. = 0.821 (Aus)

4. at =0.05 two tailed, pralue = 0.424 ; Heu lence; Can not Reject Ho (Not enough evidence) 5. Effect size can be calculated as Xw - TE S (n-1) +(12-1) SE (the) da Where S 8x6.44 + 8x 46.52 =) da 41356-17.2 31.295 18 0.41 (Aus) = 31.295 the measures t test revealed that 6. Independent participants 'Western Ca M = 4.3556 , which are $$ = 381.6622) and Eastern" (M = 3.0889,88 = 154 • 8981) their GDP is not different ; ta p = 0:424 70.05 two tailed d=-0.411 t = -0.82. and (Aus if Please: upvote; like you my answer.
