  3. AN OVERVIEW OF THE HYPOTHESIS TESTING Hypothesis Testing: An Overview <BASIC STATISTICS – HYPOTHESIS TESTING> For your questions, comments, and suggestions, please e-mail us at izecool_mint22@yahoo.com. More power to New Era University!!!

  4. Hypothesis • Hypothesis - An Educated Guess • Null Hypothesis – empty or resulting to zero results • Alternative Hypothesis – an option or choice • Research – systematic search using various tools Hypothesis Testing: An Overview <BASIC STATISTICS – HYPOTHESIS TESTING> For your questions, comments, and suggestions, please e-mail us at izecool_mint22@yahoo.com. More power to New Era University!!!

  5. T-Test • Testing differences between 2 means proportion etc., S.D. taken from the sample Hypothesis Testing: An Overview <BASIC STATISTICS – HYPOTHESIS TESTING> For your questions, comments, and suggestions, please e-mail us at izecool_mint22@yahoo.com. More power to New Era University!!!

  6. Testing Hypothesis: Step 1 • Formulate a null hypothesis & alternative null (H0) – there is NO significant differences between X1-X2 • Alternative (H1) there is significant differences x1>x2 │x1<x2, x1≠x2 Hypothesis Testing: An Overview <BASIC STATISTICS – HYPOTHESIS TESTING> For your questions, comments, and suggestions, please e-mail us at izecool_mint22@yahoo.com. More power to New Era University!!!

  7. Step 2: • df = n1 + n2 – 2 Step 3: • Tabular value Step 4: • Computed “ t ” Hypothesis Testing: An Overview <BASIC STATISTICS – HYPOTHESIS TESTING> For your questions, comments, and suggestions, please e-mail us at izecool_mint22@yahoo.com. More power to New Era University!!!

  8. Step 5 • Conclusion: T computed > that reject H0 T computed < that accept H0 Hypothesis Testing: An Overview <BASIC STATISTICS – HYPOTHESIS TESTING> For your questions, comments, and suggestions, please e-mail us at izecool_mint22@yahoo.com. More power to New Era University!!!

  9. F-Test • Analysis of Variance (ANOVA) ─ Testing difference among 3 or more groups treatments, sample or population means or proportion.

More power to New Era University!!!

  10. Formulae: • SStr = T12 + T22 + T32 – T2 N1 N2 N3 N where: SStr = sum of squares of treatment T1,T2,T3 = sum in each column T = total of all items or entries N = total number of items Hypothesis Testing: An Overview <BASIC STATISTICS – HYPOTHESIS TESTING> For your questions, comments, and suggestions, please e-mail us at izecool_mint22@yahoo.com. More power to New Era University!!!

  11. SSt = Σx2 – T2 N Where: SSt = total sum of squares Σx2 = x21 + x22 + x23 ....... x2n Hypothesis Testing: An Overview <BASIC STATISTICS – HYPOTHESIS TESTING> For your questions, comments, and suggestions, please e-mail us at izecool_mint22@yahoo.com. More power to New Era University!!!

  12. SSe = SSt - SStr Where: SSe = sum of squares of error Hypothesis Testing: An Overview <BASIC STATISTICS – HYPOTHESIS TESTING> For your questions, comments, and suggestions, please e-mail us at izecool_mint22@yahoo.com. More power to New Era University!!!

  13. Mean Sum of Squares • Treatment: MSStr = SStr K – 1 where: MSStr = mean sum of squares of treatment K = number of column K – 1 = degrees of freedom of numerator Hypothesis Testing: An Overview <BASIC STATISTICS – HYPOTHESIS TESTING> For your questions, comments, and suggestions, please e-mail us at izecool_mint22@yahoo.com. More power to New Era University!!!

  14. MSSe = SSe N – K where: MSSe = mean sum of squares of error N – K = difference denominator Computed value of F Fc or F ration Fc = MSStr MSSe Hypothesis Testing: An Overview <BASIC STATISTICS – HYPOTHESIS TESTING> For your questions, comments, and suggestions, please e-mail us at izecool_mint22@yahoo.com.
