Research question

You should phrase your research question in a way that matches up with the scope of inference your dataset allows for.

Does climate change affect worldwide weather more in the Northern or Southern Hemisphere?

Cases

What are the cases, and how many are there?

There are 324647 elements of data from 194 different countries.

Data collection

Describe the method of data collection.

The kaggle data was compiled using the site Meteostat.net. This website has open source data collected from thousands of weather stations worldwide

Type of study

What type of study is this (observational/experiment)?

This is an observational study.

Data Source

If you collected the data, state self-collected. If not, provide a citation/link.

The data was retrieved in kaggle.

Dependent Variable

What is the response variable? Is it quantitative or qualitative?

The Explanatory variables are temperature, windspeed and air pressure.

Independent Variable(s)

The independent variable is location.

Relevant summary statistics

Provide summary statistics for each the variables. Also include appropriate visualizations related to your research question (e.g. scatter plot, boxplots, etc). This step requires the use of R, hence a code chunk is provided below. Insert more code chunks as needed.
