What is this chart? Pie chart What type of variable used for? Nominal Categorical Ordinal Categorical What is this chart? Frequency Polygon What type of variable used for? Continuous Variable Discrete Variable Measures of central tendency are: Mean Median Mode Pie Chart: Type of graph: What is this chart? Bar chart What type of variable used for? Nominal Categorical Variable Ordinal Categorical Variable Discrete quantitative Variable Name of colour What are the five numbers it shows? * 1. Minimum * 2. Q1 * 3. median * 4. Q3 * 5. Maximum * Outliers/single data point What is this chart? * Histogram What type of variable used for? * Continuous Variables Measures of dispersion (variation) Range Inter quartile Range Variance Standard Deviation Coefficient of Variation Histogram of A & C What is the difference between these two histograms? Group C has more dispersion than Group A. The values for Group C are more spread out. More Dispersion (High Variation) Values are less similar to each other. Spread out distribution Less Dispersion (Low Variation) Values are more similar to each other. More closed distribution Narrow range (Less dispersion) Data/values less heterogeneous Values more similar to each other Wide range (More dispersion) Data/values more heterogeneous Values less similar to each other The histograms centre on the same value of 50, but the spread of values is is notably different. The values for group A mostly fall between 40-60 while for group B that range is 20-90. The mean does not tell the entire story! At a glance, the difference is evident in the histograms. In short, histograms show you which values are more and less common along with their dispersion. You can't gain this understanding from the raw list of values. Summary statistics, such as the mean and standard deviation, will get you partway there.
