One of the disturbing uses of statistics in the media is taking statistical information and displaying the information in an exaggerated manner to trick the reader into a certain point of view. On pages 98-100 of your textbook, pick one of the following problems:1, 2, 3a, 4a, 5, 6, 7a, 8, 9, 13, or 15. Discuss how the graph is misleading. Why might the graph’s creator have made the graph this way? How could the graph be improved to show the information in an unbiased manner? Do you think it is unethical to portray information in this way? Why or why not?

1) Select 1 variable as the response variable. Select one continuous and one categorical variable as explanatory variables. Report your variable choices.
Compute and interaction term , in JASP, by multiplying together the categorical variable with the continuous variable independent variable.
You will use both independent variables and the computer interaction term in the regression analysis
Complete the following:
1) Run a regression test. Report all 3 output tables
2) Is there an interaction effect detected? Explain
3) Run the analysis without the interaction term. Report the 3 resulting regression tables
4) How has the output changed? (R, Adjusted R squared, ANOVA table p-value, and Coefficient table p-values)

DIRECTIONS for Initial Post
1) Select the ONE continuous variable from the database to use. State your choice
2) Select ONE categorical variable from the database (your choice). State your choice
3) Generate a random sample of 20 records from each of your levels of categories for your variable selected in #2. Post the file (in .csv format) , that contains only your generate random sample, to your post
4) Generate a descriptive statistics table by groups from your sample. Post your descriptive statistic table , in APA format, to this thread.
5) Using your sample, generate a series of boxplots within ONE CHART which shows the spread of the continuous variable (from #1) for each group of your category variable.
6) In JASP or Excel run a one-way ANOVA test, using the continuous variable, over the groups of your selected categorical variable. Copy and paste your ANOVA tables into your post.
7) Use complete sentences to write an interpretation of the p value from your ANOVA table. What does your p-value results suggest about the groups ?

Scenario:
A generation ago, people used to see their doctor only
Instructions
Scenario:
A generation ago, people used to see their doctor only when they were sick or dying. Today, preventative health care is becoming commonplace as people become more educated and empowered about their own health. Regular, routine medical check-ups can help find potential health issues before they become a problem. Early detection of problems gives the best chance for getting the right treatment quickly, avoiding any complications.
You have been employed as part of an active public health campaign that is aiming to increase routine 12-monthly check-ups. Your job is to identify groups of people with lower rates of check-ups in the last 12 months where a targeted campaign would be of most benefit.
The Behavioral Risk Factor Surveillance System (BRFSS) is a collaborative project between all of the states in the United States (US) and participating US territories and the Centers for Disease Control and Prevention (CDC). The BRFSS is a system of ongoing health-related telephone surveys designed to collect data on health-related risk behaviours, chronic health conditions and use of preventive services from the non-institutionalised adult population (≥18 years) residing in the United States. Using the prepared BRFSS data, identify demographic, social and behavioural factors that are associated with routine check- up attendance.
Dataset:
BRFSS 2024 data
Format:
Your written briefing document must consist of a 250-word executive summary and a detailed structured results section. This template will assist you with the format and information required.
Executive Summary (Marks: 25)
The 250-word summary should identify demographic, social and behavioural factors that are associated with routine check-up attendance in a statistically valid, clear and concise manner that can be understood by someone with minimal knowledge of epidemiology and biostatistics. You must identify a group or groups of people where a targeted campaign would be of most benefit.
Results:
The BRFSS:
A short summary of the study design of the BRFSS and a brief discussion of its limitations (no more than 250 words (Marks: 6)
Find a peer-reviewed primary quantitative research study in the literature that investigates the determinants of routine check-up attendance. Compare the designs between the study described in that paper and BRFSS (not more than 150 words). (Marks: 4)
Description of the population and analysis:
1) By analysing the BRFSS dataset, answer the following questions:
In your dataset, what percentage of participants reported routine check-up attendance? (Marks: 5)
Create a table of routine check-up attendance and 3 demographic factors, one of which must be binary, one numerical and one multi-category categorical (either nominal or ordinal). (Marks: 15)
Each cell should contain the appropriate summary measure and 95% confidence interval
The final column in the table should contain the p-value for statistical tests of difference or independence (i.e., tests that we covered in week 6). Footnotes should be used to indicate which statistical tests were used.
2) Examine the association between 4 social and/or behavioural factors and routine check-up attendance:
In an appropriate manner, present the results of analysis into the effect of four social and/or behavioural factors on routine check-up attendance. You must analyse a binary, numeric, nominal and ordinal factor. (Marks: 20)
For each factor you should report:
Variable name and data type
Name of measure calculated
Results of statistical analysis performed
Statistical interpretation
The Stata output (including visible code) e.g.
For one of the identified factors, you should explore the possibility of confounding or effect modification by sex. (Marks: 10)
Perform appropriate analysis
Present STATA output (including visible code)
Report the results in a table
Interpret your result
Conduct a multivariable regression and present the results of the adjusted regression model by including the four factors you examined in your analysis of social and behavioural factors. (Marks: 10)
Present STATA output (including visible code)
Report the results in a table.
Interpret your result
