Topics in Statistics

1

Mean vs Median - Understanding the Difference

  • Mean can be misleading when extreme values (outliers) are present in the data
  • Median is the middle value when data is arranged in ascending order
  • Median is less affected by extreme values compared to mean
2

Median from Frequency Tables

  • Use cumulative frequency to find median position
  • Median position for n observations = (n+1)/2 for odd n, n/2 and (n/2+1) for even n
  • Find the class containing the median using cumulative frequency
3

Median from Grouped Data (Class Intervals)

  • When data is grouped in classes, we assume uniform distribution within each class
  • Find the median class using cumulative frequency
  • Use interpolation to find exact median value within the median class
4

Problem Solving Strategies

  • Identify the type of data: individual values or grouped data
  • Choose appropriate method based on data type
  • Always verify your answer makes logical sense
