- - - - Distribution:
        
        Frequency Distribution
        
        Normal / Gaussian Distribution
      - Central Tendency: Estimate of center of distribution of values
        
        Mean: Average of the set of values;
        Mean = 167/8 = 20.875
        
        Median : score found at the exact middle of the set of values
        Median= 20+20/2 = 20
        
        Mode: most frequently occurring value in the set of scores
        Mode=15
      - Dispersion: Spread of value around central tendency
        
        Range: the highest value minus the lowest value.
        Range= 36-15 = 21
        
        Standard Deviation: square root of variance by determining each data point's deviation relative to the mean.
        Note:
        The Standard Deviation is bigger when the differences are more spread out
        We can expect about 68% of values to be within plus-or-minus 1 standard deviation
        
        Population Standard Deviation: Divide Sum of squared distance from mean by N
        
        Sample Standard Deviation: Divide Sum of squared distance from mean by N-1
        
        Variance: The variance (σ2), is defined as the sum of the squared distances of each term in the distribution from the mean (μ), divided by the number of terms in the distribution (N).
