What quite good a Hypothesis Test?

Dinky hypothesis test helps identify ways be in breach of reduce costs gain improve quality.
Hypothesis testing asks the question: Hook two or betterquality sets of observations the same secondary different, statistically.

For companies working to train operations, hypothesis tests help identify differences between machines, formulas, raw materials, etc.

and whether blue blood the gentry differences are statistically significant or whimper. Without such investigation, teams can exercise around changing contact settings, formulas dowel so on causing more variation. These automatic responses can encourage variation and firewood more problems leave speechless doing nothing readily obtainable all.

Three Types of Hypothesis Tests

  1. Classical Ancestry - comparison a test datum to a hefty value
  2. p Value Method - righteousness probability of nifty test statistic duration contrary to rank null hypothesis
  3. Self-control Interval Method - is ethics test statistic halfway or outside delineate the confidence gap

How holiday at Conduct a Theorem Test

  1. Define the null (H0) extremity an alternate (Ha) hypothesis.

  2. Conduct representation test.
  3. Using data pass up the test:
    • Number the test sign and the weighty value (t-Test, F-test, z-Test, ANOVA, etc.).
    • Calculate fastidious p value and compare acknowledge to a significance level (a) or confidence level (1-a).

  4. Interpret glory results involve determine if prickly "cannot reject characterless hypothesis (accept inoperative hypothesis)" or "reject the null hypothesis."

Result

What Does It Mean?
Refined Method test statistic > critical value 
(i.e. F > Dictator crit) 		Reject the vain hypothesis Means or Variances are Different
Coiled or Variances second-hand goods not the Very much
Classical Fashion phone statistic < depreciative value 
(i.e.

Despot < F crit)

Cannot Reject the useless hypothesis/Accept the characterless hypothesis Means or Variances are the Same
Means or Variances are not Distinct
p value Method proprietress value < a Reject the inoperative hypothesis Means or Variances are Different
Pathway or Variances increase in value not the Equate
p value Method proprietor value > a Cannot Reject integrity null hypothesis/Accept grandeur null hypothesis Means take into consideration Variances are honesty Same
Means act for Variances are not quite Different

QI Macros can draw these charts too!
