Week 10 Reflections_Annisa Ardiani

Which of these research designs are used for national surveys?     Cohort     Cross-sectional     Quasi-experimental     Case-Control

Please read the article and answer the following questions thanks

What is the difference between the population and sample regressionfunctions? Is this a distinction without difference?

Please help me figure out this question

Provide an example of a research project in your hometown where the one-sample chi-square test would be the most appropriate statistical technique to use. How would you make it a two-sample chi-square test?

Is there a relationship between one’s gender and whether one owns a dog, cat, or reptile? Use the data provided in the table below to answer the following question. -Show all the relevant statistical output How do I enter this data in SPSS and which test do I run? I input one column for each level but I am so confused and my output is weird looking. Do I run the One Way ANOVA in order to be able to calculate the effect size?      Dog Cat Reptile Row Totals Male 20 17 11 48 Female 25 23 5 53 Column totals 45 40 16 101

can ridge regression be applied if sample size is smaller than the number of predictors?

Based on statistical analysis, are we justified in asserting that two variables are statistically dependent? Why or why not? Explain why researchers typically focus on statistical independence rather than statistical dependence.

A researcher is implementing an intervention where parents are taught advocacy skills.  Fifteen parents are participating in the study and 15 parents are members of the control group. All 30 parents complete an empowerment scale, which is measured on a multi-item Likert scale.  The researchers want to determine if there is a difference between the two groups of parents (intervention, control) on their empowerment score.  What type of statistical test should be used?   Group of answer choices Independent t-test Dependent t-test Chi Square ANOVA Correlation Analysis

Which of these sounds like a situation where you would want to use an Independent-Measures ANOVA? A) Comparing the health of students at a campus with a Student Health Center vs. students at a campus without a Student Health Center B) Comparing the technological ability of a group of children when they are 10 years old vs. when they reach 15 years old vs. when they reach 20 years old C) Comparing the pain levels of people with an anti-arthritis drug vs. the pain levels of the general population of all arthritis patients D) Comparing the technological ability of three groups: people born in the years 2000, 2005 and 2010

The data provided in the following table pertains to three separate questions: One sample T-test, Two Sample T-Test, and ANOVA. The same data is also provided in Microsoft Excel file. Answer the questions provided in the table. Report your results by comparing the significance level to 5%. Additionally, state your conclusion clearly in terms of whether the null hypothesis is rejected or not rejected. Avoid using terms like "accepted" or "not accepted" in your conclusion. Question 1: A retail store manager claims that the average daily sales of the store are $1,500. You aim to test whether the actual average daily sales differ significantly from this claimed value.  (2 points = 0.25x4 parts) Make null and alternative hypothesis for one sample T-test     Conduct One Sample T Test and provide a snapshot of results from excel. Null = Alternative = Conclusion: Since the p value is (choose one: less / greater) than 5%,
