Question: What is the best way to visualize time estimates? Which graph type should one choose?
I have time estimates how long did it take different people to finish the same task. An estimate might be 16 units of time as well as a rough estimate 15 to 20 units of time. I can assume that the values will be positive integers ranging from 1 to 50 and there are 50 datapoints in total.
Example data might look like:
person 1: 7 time units
person 2: 1 to 3 time units
person 3: 42 time units
What is the best way to visualize such data? One possible solution would be to take averages of the time intervals (rough estimates) but is there a smarter way of visualization?
A am a programmer so I do not care about the input format. Also I do not have a preference what software should be used, although open-source is a plus. I would go with Python, R, Gnuplot or LibreOffice Calc, but I do not know which type of graph to choose.
Edit: The goal is to see how much time did the task took on average and what was the distribution. Sorry for possibly wrong question, but I am new to plotting and statistics.
