What kind of test is used for this problem? How is it solved step by step?
Devise two scenarios where a dependent/matched/paired t-test would be appropriate. Be sure to express how you would measure your dependent variable.
You should use a webpage to find the test stat for this problem, Also look at the p-value if the p-value is less than 0.05 there is strong evidence the variables are dependent (there is a difference in proportions). The following data set is the results of some market research were some people were shown one ending (ending 1) and other people were shown a different ending (ending 2), they were asked if they like the product (yes or no) Yes they liked the ending No they did not like the ending ending 1 15 85 ending 2 75 25 Which option below has all the correct options to the chi square test of independence?
Below you will find a research scenarios. Your task is to identify the proposed analysis and why you chose that analysis for each of these scenarios. State the research question that aligns with the scenario and the analysis. Next run the appropriate analyses and report your findings in APA Research scenario 2: Historians are interested in the accuracy of eyewitness accounts of traumatic events. One study examined survivors' recall of the sinking of the ship Titanic (Riniolo, Koledin, Drakulic, & Payne, 2003). The researchers reviewed the transcripts of survivors' testimony at governmental hearings (www.titanicinquiry.org) to see whether they testified that the ship was intact or breaking apart during the ship's final plunge (it was in fact breaking apart). To test for eyewitness accuracy, testimony of 20 survivors was examined to see if there was an equal likelihood of survivors saying the ship was intact or breaking apart.

A preschool teacher is interested in whether the type of math program used impacts learning. One class receives a workbook to complete at home and another class receives an interactive app. The preschool teacher then compares whether those who received the interactive app versus the workbook perform better on a math test (percentage correct). Identify the independent variable and the operational definition Identify the dependent variable and the operational definition. Below you will find data for this experiment. Draw a histogram for each of the math programs. Determine if the data for each condition presents any skewness or kurtosis properties. Compute the following for each condition below: ∑X ∑(X)2 ∑X2 ∑(X-1) ∑(X-1)2 Workbook X f 80 2 79 2 75 3 81 1 60 5 65 6 75 8 App X f 90 5 80 3 82 4 94 3 78 2 93 4 92 6
Read through this scenario and look at the data that was collected. State the null and all possible research hypotheses. Review the results below (I used SPSS) and answer the questions that follow. Scenario: A researcher wants to see if gender and/or income affect the total amount of help given to a stranger who is sitting on the side of a busy road with a sign asking for help. The independent variables are gender, income, and the interaction of gender and income. The dependent variable is total help. He wants to know if one or both factors – or the interaction of the two - affect the total amount of help offered. Because he is analyzing two independent variables (gender and income), he used a factorial ANOVA. His results show the main effect of each of the independent variables on the dependent variable (total help) and the interaction effect. The researcher is using a 95% confidence interval which means that he wants to be at least 95% sure that his independent variables…
If presenting results of a study regarding the cinquefoil of plant height of 3 plant gardens, contrast which statistical measures you have calculated are most effective at describing the height of these plants. Think about the pros and cons of each statistics measure, if you could only report 2 or 3 values, which would they be? Why?
Alyssa is interested in testing whether pet owners and non-pet owners differ in health status. To test this question, Alyssa collects data from 100 randomly selected people and assesses whether or not they own a pet and if they are healthy or unhealthy (the data are shown in the table). What decision should Alyssa reach regarding her hypothesis? How big is the effect size? Complete the six steps of hypothesis testing. Show your work for each step. Report your results and conclusion in APA style. Assume that alpha is .05. Healthy Unhealthy Pet Owner 33 22 Non-Pet Owner 14 31
Design your own within-subjects study. Remember to include your hypothesis, independent variable with at least 3 conditions, how long participants would spend in the conditions, and your dependent variable.
Our goal is to see whether the global temperatures has been getting higher. For the phrase above, assume the data has already been presented and state a hypothesis. Describe the process one should take to test the hypothesis in detail. How should someone plan to test a hypothesis? Under what circumstances can somebody conclude that the global temperatures has been getting higher?
