In the case of applied research analysis, it's wise to avoid choosing a blanket approach. As @Michael Lai mentioned, your hypothesis / research question should drive your choice of statistical method and Jeff Sauro's blog is a good resource. (I'll avoid my tirade about the lack of real hypothesis testing in UX research for later because it sounds like you ...

It doesn't matter where the cutoff is. 55.0000000000000000000000001 is still over 55. As for how to count 45-55 vs 55-65; you generally start counting at whole integers.

My suggestion is about UX, rather than on UI and visualization. Your job is to solve a problem, not make a picture. This is from the Three charts are all I need, as well as the following quote: You can spend days, weeks, or even months working on visualizations of data, but does that benefit the business most? In most cases, a simple visualization will ...

I am surprised that there aren't more people responding to this question because there is definitely a need for more rigour around statistical analysis in usability testing. I think you'll find some good resources from Jeff Sauro from MeasuringU, who seems to be one of the people that does a lot of consulting work in this area. I like most people, know ...

Candle Stick bar charts with x-axis being time & y-axis being dollar would be a suitable graph. https://en.wikipedia.org/wiki/Candlestick_chart
