Let’s look at a few examples of how correlation leads people to wrongly assume causation in real-life situations. Example 1: Business. To Check the Manufacturing Processes. Correlational research example You investigate whether standardized scores from high school are related to academic grades in college. In real life, it was found that there is a limited degree of correlation. Nonetheless, it's fun to consider the causal relationships one could infer from these correlations. Stronger relationships produce correlation coefficients closer to -1 and +1 and regression models that have higher R-squared values. Here let us look at real-life application represented by scatter plot. Examine the relationship between covariance and correlation, learn the covariance and correlation formulas, and see examples. The following examples illustrate scenarios where two variables have no correlation. Each point on a scatter plot represents one sample item at the intersection of the x Example 2: Antibiotic exposure during first year of life & weight gain in early childhood. Box Office Revenue If we collect data for the total number of Master’s degrees issued by universities Correlation simply indicates that two variables move in the same direction and doesn't necessarily suggest that one causes the other to change. ; Driving speed and travel Let’s explore examples of linear relationships in real life: 1.
