1. GOOD MORNING CLASS

2. Online Classroom Rules: Find a quiet place free of distractions (TV, parents, toys, pets, siblings, etc.).
Show up in time for class and wait to be admitted into it if needed.
Be respectful at all times when your video is on. No inappropriate language or hand gestures.
Stay on mute. Click the “raise hand” button if you have a question or something to share.
Stay on task and focused so you don’t miss anything the speaker says.

22. Describing Relationship

23. There are two ways of describing the relationships of the scores of the students in two or more subjects: using the correlation coefficient and the graphical representation of the scores in the distribution.

24. Correlation- refers to the extent to which the distributions are linearly related or associated between the two variables. The extent of correlation is indicated numerically by the coefficient of correlation or ®. The correlation coefficient ® is also known as the Pearson Product-Moment Correlation Coefficient in honor of Karl Pearson who developed the said formula. The correlation coefficient ranges from 1 to +1.

25. There are three kinds of correlation based on correlation coefficient: (1) positive correlation; (2) negative correlation; and (3) zero correlation. There are two ways of identifying the correlation between the two variables: (1) using the formula; and (2) using the scatter plot or scatter gram.

26. Positive Correlation High scores in distribution x are associated with high scores in distribution y. Low scores in distribution x are associated with low scores in distribution y. This means that as the value of x increases, the value of y increases too or as the value of x decreases, the y-value also decreases.

27. The scattergram of a positive correlation is shown in figure 1.

28. Negative Correlation Low scores in distribution x are associated with high scores in distribution y. The High scores in distribution x are associated with low scores in distribution means that as the value of x increases, the value of y decreases or when the value of x decreases, the value of y increases.

29. The scattergram of a negative correlation shown in figure 2

30. Zero Correlation As Math scores increase, Science scores decrease. Using the given points in the coordinate plane, a straight line downward to the right can be drawn that is best fitted to all the points. Hence, the slope of the line is negative. Zero correlation means that there is no association between the scores in distribution x and distribution y. No single line can be drawn that best fits to all points, or no discernible pattern can be formed as shown in figure 3

31. Activity Instructions: Solve the given numerical data, create a scatterplot, and determine whether the correlation is positive, negative, or zero.
