Organising and Graphing Data

Organising and Graphing Data

1. Quantiative

   • Numerical Data
     • Discrete
       • whole numbers
         • Histogram
     • Continueous
       • Part Numbers ie 5.4
         • Histogram
     • Time Series
       • Data Collected thru time ie: Sales data
         • Graph to use: 1. Line Graph 2. Scatterplot
     • Cross Sectional
       • Data collected at a number of different points ie Capital City Temperatures
         • Graph to use: Scatterplot
   • Tables: Summary/Frequ Dist Relative Frequency
   • Graphs: Histogram Line Graph Scatter Plots Box Plot

2. Qualitative

   • Non-numeric (categorical)
     • Nominal
       • ie surveys - boat, train, walk etc
     • Ordinal
       • ie Poor, Average, Good, Very Good
   • Tables: Summary/Frequ. Dist Relative Frequency
   • Graphs: Pie Graph Bar Graph

3. Bivariate Data

   • Data with two variables
     • Qualitative BV data
       • Contingency Table
         • Graphs: Clustered or Stacked Bar-graph
     • Quantitative BV data
       • Scatterplot
