Research Question

I am interested in analysing impact of variables like urabnisation, female employment, carbon emission and oil consumption per capita on breast cancer in females. All the explanatory variables used have high correlation with stress and environmental pollution. Is there a relationship between increasing stress and air pollution on breast cancer in females?

Bivariate analysis

Categorical vs Quantitative

This graph supports our hypothesis as countries with large urban population have more breast cancer cases.

This doesn turned out as expected but this maybe possible due to less data points for countries with higher female employement rate. So, we didnt get any conclusive evidence as above.

This supports out hypothesis as we are getting that increased carbon emission have more breast cancer cases.

This is not turned out as expected maybe be due to beacause this variable doesnt capture the stress as we supposed it to.

Quantitative vs Quantitative Graphs

we can see week positive correlation between these variables supporting our hypothesis

No conclusive evidence

this plot doesnt makes the picture as clear as in the above case

No conclusive evidence

Summary

Hypothesis

Stress increase and exposure to pollution can cause increase breast cancer cases.

Variable of focus in data set:

Response variable = breastcancerper100TH Explanatory variable = femaleemployrate Explanatory variable = co2emissions Explanatory variable = suicideper100TH Explanatory variable = urbanrate In the available dataset unique identifier of a data point is country.

Except the breast cancer variable all other variables are included to capture the features of stress and pollution.

Week 4 – Assignment

The primary purpose of the Concept Paper is to obtain instructor feedback to ensure that you are on track with the completion of your feasibility study. The complete instructions for the feasibility study can be found in Week Six of the online course.The Concept Paper is a draft version of your Final Paper with the initial list of relevant scholarly sources. In this draft, be certain to include…

This week, you will select a research topic for your Final Project and submit it to your Instructor for approval. Your topic should be related to gender, and the research that you conduct on the topic (in future weeks) should be from a psychological perspective. The following are examples of research topics:

Academic achievement gap in math test scores between boys and girls

SUMMARY

(1)   The first graph is unimodal, with its highest peak at the category of $0 to $2000 income per person. It seems to be skewed to the right as there are higher frequencies in lower categories than the higher categories.

(2)    The second graph is unimodal, with its highest peak at the category of 40% to 60% female employ rate. It seems to be skewed to the right as there are higher frequencies in lower categories than the higher categories.

(3)   The third graph is unimodal, with its highest peak at the category of 0% to 20% internet use rate. It seems to be skewed to the right as there are higher frequencies in lower categories than the higher categories.
