Title: Testing a number served as an anchor on urban college students

Abstract:

Introduction:

Alternative Hypothesis: Based on previous work there will be a difference in the number of groups guesses of departments means due to the anchor.

Null Hypothesis: There will be no difference in means between groups due to the anchor.

• Methods: Participants,Equipment,Materials,Variables

Results: add the following and add the chart provided describing results of mean, t-test and significance level

Results: Present means between two groups. Present T test level and how it supports our hypothesis and significant because value is less than .05 Previous work supports hypothesis.

Condition 15 or 100

T value= -2.4 significance (.05 or less) -2.4/100 by chance

Reject null hypothesis

Anchor (independent) variable two levels (15) and (100)

Dependent (number of departments chosen by students) The guesses

Discussion-

Further study we may conduct: (will they ignore the anchor or not) can people over look the information.

Steps to Complete Week 5 Lab

Use the Weeks 3 and 5 spreadsheets from the Weeks 3 and 5 Lessons to help you answer the questions below.

Step 1: Your instructor will provide you with 10 values to use for this lab.

Gather 10 MORE of your own to add to the 10 provided by your instructor. Do the following:

Survey or measure 10 people to find their heights. Determine the mean and standard deviation for the 20 values by using the Week 3 Excel spreadsheet. Post a screen shot of the portion of the spreadsheet that helped you determine these values. How does your height compare to the mean (average) height of the 20 values? Is your height taller, shorter, or the same as the mean of the sample?

Note: The following image is just an example. They are NOT the values you should be using for your lab. Your instructor should have sent you our data values for your Week 5 Lab. Please reach out to your instructor if you do not have your data values.

Data Example of 10 people with different heights

(your spreadsheet will have 20 values—10 from your instructor and 10 from your own data gathering).

Step 2: Give some background information on the group of people you used in your study. You might consider using the following questions to guide your answer.

How did you choose the participants for your study? What was the sampling method: systematic, convenience, cluster, stratified, simple random?

What part of the country did your study take place in?

What are the age ranges of your participants?

How many of each gender did you have in your study?

What are other interesting factors about your group?

Step 3: Use the Week 5 Excel spreadsheet for the following.

(Use the Empirical Rule tab from the spreadsheet). Determine the 68%, 95%, and 99.7% values of the Empirical Rule in terms of the 20 heights in your height study.

What do these values tell you?

Post a screen shot of your work from the Week 5 Excel spreadsheet.

Week 5 Spreadsheet Example

(Use the normal probability tab from the spreadsheet). Based on your study results, what percent of the study participants are shorter than you? What percent are taller than you?

Post a screen shot of your work from the Week 5 Excel spreadsheet.

Example: If my height is 73 inches, then 20.86% of the relevant population is shorter. The other 79.14%, of course, is taller.

Hi, Please write a research proposal on any topic related to environmental issues.

**In this proposal, please use methodology 1. Quasi-experimental methods: Difference-differences. OR. 2. Quasi-experimental methods: Regression discontinuity design.

You should include 1. TITLE. 2. BACKGROUND AND RATIONALE. 3. RESEARCH QUESTION(S). 4. RESEARCH METHODOLOGY 5. Hypothesis

Hello, please edit the answer according to the hints on the home page when you are doing the question. The screenshot is in the correct format as requested by my professor. Most of the answers can be found online, such as Chegg. But I want the questions that require text answers to be written in the correct form that my professor requires.

You have been hired by the D. M. Pan National Real Estate Company to develop a model to predict housing prices for homes sold in 2019. The CEO of D. M. Pan wants to use this information to help their real estate agents better determine the use of square footage as a benchmark for listing prices on homes. Your task is to provide a report predicting the housing prices based square footage. To complete this task, use the provided real estate data set for all U.S. home sales as well as national descriiptive statistics and graphs provided.

Directions

Using the Project One Template located in the What to Submit section, generate a report including your tables and graphs to determine if the square footage of a house is a good indicator for what the listing price should be. Reference the National Statistics and Graphs document for national comparisons and the Real Estate Data Spreadsheet spreadsheet (both found in the Supporting Materials section) for your statistical analysis.

Note: Present your data in a clearly labeled table and using clearly labeled graphs.

Specifically, include the following in your report:

Introduction

Describe the report: Give a brief descriiption of the purpose of your report.

Define the question your report is trying to answer.

Explain when using linear regression is most appropriate.

When using linear regression, what would you expect the scatterplot to look like?

Explain the difference between predictor (x) and response (y) variables in a linear regression to justify the selection of variables.

Data Collection

Sampling the data: Select a random sample of 50 houses. Describe how you obtained your sample data (provide Excel formulas as appropriate).

Identify your predictor and response variables.

Scatterplot: Create a scatterplot of your predictor and response variables to ensure they are appropriate for developing a linear model.

Data Analysis

Histogram: Create a histogram for each of the two variables.

Summary statistics: For your two variables, create a table to show the mean, median, and standard deviation.

Interpret the graphs and statistics:

Based on your graphs and sample statistics, interpret the center, spread, shape, and any unusual characteristic (outliers, gaps, etc.) for the two variables.

Compare and contrast the shape, center, spread, and any unusual characteristic for your sample of house sales with the national population. Is your sample representative of national housing market sales?

Develop Your Regression Model

Scatterplot: Provide a scatterplot of the variables with a line of best fit and regression equation.

Based on your scatterplot, explain if a regression model is appropriate.

Discuss associations: Based on the scatterplot, discuss the association (direction, strength, form) in the context of your model.

Identify any possible outliers or influential points and discuss their effect on the correlation.

Discuss keeping or removing outlier data points and what impact your decision would have on your model.

Find r: Find the correlation coefficient (r).

Explain how the r value you calculated supports what you noticed in your scatterplot.

Determine the Line of Best Fit. Clearly define your variables. Find and interpret the regression equation. Assess the strength of the model.

Regression equation: Write the regression equation (i.e., line of best fit) and clearly define your variables.

Interpret regression equation: Interpret the slope and intercept in context.

Strength of the equation: Provide and interpret R-squared.

Determine the strength of the linear regression equation you developed.

Use regression equation to make predictions: Use your regression equation to predict how much you should list your home for based on the square footage of your home.

Conclusions

Summarize findings: In one paragraph, summarize your findings in clear and concise plain language for the CEO to understand. Summarize your results.

Did you see the results you expected, or was anything different from your expectations or experiences?

What changes could support different results, or help to solve a different problem?

Provide at least one question that would be interesting for follow-up research.
