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 coeffic...
