Data preparation Time - data preparation 80%, and everything else falls into about 20% GIGO - garbage in, garbage out. That's a truism from computer science. The information you're going to get from your analysis is only as good as the information that you put into it Upside to In-house data - It's the fastest way to start., you may actually be able to talk with the people who gathered the data in the first place. Downside to In-house data - if it was an ad-hoc project, it may not be...

Analyses for Data Science: Descriptive: - Humans are good at finding patterns, but limited bandwidth - so we need to narrow the data. Look at the data. 1) Visualize the data - graphs, histograms, bell curve 2) Compute Univariate Descriptive Statistics: mean (average), mode (most common), median (splits into two equal halves). So ONE Value. 3) Measures of association: connection between the variables in your data. Range: high and low, Quartiles, Variance, Standard Deviation, Correlation coeffi...
