    Correct answer is 0.865.......thanku so much mam for such a wonderful explanation.....

  • @_m3n4v
    @_m3n4v 2 місяці тому +6

    submission x = 80, y= 100
    mean of x = 16,y=20
    submission(x-x bar)(y- y bar) = 84
    submission(x-x bar) square = 118, submission(y - y bar ) square = 80
    according to formula : 84 / square root of 118 * square root of 80 = 84/10.86 * 8.94 = 84 / 97.088
    ans = 0.865

    Literally you are a saviour...i didnt have any idea about correlation and by just watching this video now the concept is clear ..really thanks to you mam..😊

    Calculating the Correlation Coefficient
    Given:
    * X: 10, 12, 15, 23, 20
    * Y: 14, 17, 23, 25, 21
    Steps:
    * Calculate the means of X and Y:
    * Mean of X (x̄) = (10 + 12 + 15 + 23 + 20) / 5 = 16
    * Mean of Y (ȳ) = (14 + 17 + 23 + 25 + 21) / 5 = 20
    * Calculate the deviations from the means for each data point:
    * For X:
    * 10 - 16 = -6
    * 12 - 16 = -4
    * 15 - 16 = -1
    * 23 - 16 = 7
    * 20 - 16 = 4
    * For Y:
    * 14 - 20 = -6
    * 17 - 20 = -3
    * 23 - 20 = 3
    * 25 - 20 = 5
    * 21 - 20 = 1
    * Multiply the corresponding deviations for each data point:
    * (-6) * (-6) = 36
    * (-4) * (-3) = 12
    * (-1) * 3 = -3
    * 7 * 5 = 35
    * 4 * 1 = 4
    * Sum the products from step 3:
    * 36 + 12 - 3 + 35 + 4 = 84
    * Calculate the standard deviations of X and Y:
    * For X:
    * s_x = √[(Σ(x_i - x̄)²)/(n - 1)]
    * s_x = √[(36 + 16 + 1 + 49 + 16)/(5 - 1)]
    * s_x ≈ 4.36
    * For Y:
    * s_y = √[(Σ(y_i - ȳ)²)/(n - 1)]
    * s_y = √[(36 + 9 + 9 + 25 + 1)/(5 - 1)]
    * s_y ≈ 4.58
    * Calculate the correlation coefficient (r):
    * r = (Σ[(x_i - x̄)(y_i - ȳ)]) / [(n - 1) * s_x * s_y]
    * r = 84 / [(5 - 1) * 4.36 * 4.58]
    * r ≈ 0.864
    Therefore, the correlation coefficient between X and Y is approximately 0.864. This indicates a strong positive correlation between the two variables.
