Warning: You need to put your "thinking cap" on. Let's do "reverse engineering"
By assuming that the following histograms and their distribution shapes are the final findings
or outcomes of your data analysis, please give the best-suited/ideal example of data (that can
come from multiple domains such as banking, education, manufacturing, etc.). Please also
provide the data description and a scenario for better understanding.
An example:
In a health sector, in particular, the COVID-19
situation where the x-axis variable can be the selected
months (say, July 2021 to March 2022), and the y-axis
variable can be the no. of positive cases, this is an ideal
situation. We can see the no. of positive cases is
reduced from the months on the left towards the
right, and therefore we can conclude that the
vaccination programme is effective/working.
Please fill in the answers for the following histograms:
