Answer
Data understanding — explore data
Options - A. Data understanding — explore data - B. Data preparation — format data, since it is done in the same sheet - C. Modelling — build model, since a histogram is a summary - D. Evaluation — evaluate results, since it shows the spread Why - A. Correct — a histogram drawn to *see* the shape is exploration. Where it is drawn does not matter; what it is for does. - B. Nothing about the table changes when you chart it. Sharing a sheet with the data does not make a look into a preparation step. - C. A histogram drawn to look is not the summary that answers the question; the model is the comparison built later. - D. Evaluation judges a result against the business criterion. There is no result yet.
