Question

You have been provided with theYield Factors- All Yearswhich contains 7 variables and you are required to write codes that determine the following:

Number of observations and features are in the dataset.
Structure and summary of the dataset.
Retrieve data for grazing land in 2016.
Create a new column – “Yield_Factor” – which is a quotient of “National_Yield” (dividend) and “World_Yield” (divisor).
Create an “infrastructure” dataset and use it to generate a scatter plot with “National_Yield” on the x-axis and “World_Yield” on the y-axis.
Create a scatter plot of “Year_2016” with the x-axis representing “National_Yield” and the y-axis representing “World_Yield” and faceted to have one subplot per “Land_type”.
Find the median national yield (National_Yield), median world yield (World_Yield) and median yield factor (Yield_Factor) within each combination of Land_type and Year.
Create a line plot showing the change in median yield factor by Land_type over time

For each of the outputs [(a) - (g)] provide a discussion of your findings - a minimum of one paragraph.
