🔍 Understanding the Z Score Test

Here’s your guide to mastering the Z Score:

  1. What’s a Z Score?:
    • It’s a statistical measurement that describes a data point’s relation to the mean of a group of data points.
    • In simpler terms, it tells you how many standard deviations away a data point is from the mean.
  2. Setting Your Level of Significance (α):
    • This determines how ‘strict’ your analysis is. Common levels are 0.05 (5%) or 0.01 (1%).
    • It’s like choosing the sensitivity level of your statistical radar.
  3. Critical Z Value – The Benchmark:
    • This is the threshold number in your Z test. If your calculated Z score is beyond this value, it suggests something significant in your data.
    • It’s like a marker that tells you when your findings are stepping out of the ordinary.
