Notes on Statistics Tool - Analysis of a Sample Population
  • Value N refers to a particular value of the variable sampled.
  • Number N refers to the frequency of the value ... i.e the number of occurrences ... for small sample populations this is generally 1.
  • Sample values with Number N = or > 1 are included in the analysis.
  • A frequency (F) histogram of sample values (V) is plotted for Total Entries > 1.
  • Results are given to three decimals places ... scale the sample values before entry for greater precision.
  • -1000000 < or = Value N < or = 1 000 000
  • 0 < or = Number N < or = 100 000
