Question:

In this assessment you will analyse data about a temperature in Adelaide. The data was collected by Australian Bureau of Meteorology – the best source of the climate related information in Australia. Two presented data set contain information about daily maximal and minimal temperatures for Adelaide weather station 023034 at Adelaide Airport. You can find these and other locations data at http://www.bom.gov.au/climate/data/index.shtml?bookmark=200

You get a chance to say your own word on the question of a climate change based on the hard-core facts from a rigorous data analysis. You must complete the required steps and provide answers on the following questions:

Write an introduction about what type of analysis you plan to execute. Provide a brief data description: what are your data about; how many variables and observations there; what are highest and lowest temperatures were observed and when?
Make a function to calculate and (nicely) present descriptive statistics (mean, standard deviation, skewness, kurtosis, median, IQR) for a given month and year. Run it for a maximal temperature for a month of your choice in 1961 and 2021. Compare results and discuss. Present appropriate data visualisation to support your discussion.
Combine two data sets together and calculate a daily range between maximal and minimal temperature. Get an average range for each year, discuss its distribution and change over the time. Provide appropriate data visualisations to support your discussion.
Count number of days per year with maximal temperature above 35 degrees. Build a graph. Discuss your observations.
Select and justify a threshold for a minimal temperature and repeat step 4 for the number of days below the chosen threshold.
Combine results from steps 4 and 5; discuss your findings and implications for the question of climate change.
Write a conclusion outlining your analysis and results.

You do not need to write too much as everyone hates reading long and/or boring reports. At the same time, if you need more space for your discussion then you can take it. There are no limits for word count or number of pages.

As a general rule, every question requires to present result in three ways – as a graph, as numbers and as text describing both. There might be exceptions when you cannot have all three, but these situations are not so common.
