Understanding Negative Covariance in Variance Analysis PPT

This PPT slide, part of the 37-slide Variance Analysis PowerPoint presentation, presents a detailed analysis of variance, focusing on the concept of negative covariance. It illustrates a scenario where one variable, such as volume, decreases while another, like price, increases. The key takeaway is that despite changes in these variables, the underlying formula for covariance remains unchanged.

The graphical representation shows 2 years, 1997 and 1998, with corresponding volume and price figures. For 1997, the volume is 9.7, while in 1998, it rises to 14.7. Price figures indicate a decrease from $18.20 in 1997 to $17.00 in 1998. This juxtaposition highlights how the relationship between volume and price can lead to negative covariance, which is crucial for understanding financial dynamics.

The calculations provided break down the impact of these changes. The volume variance is calculated as $91.0 million, indicating a positive contribution to total variance. Conversely, the price variance shows a negative impact of -$11.6 million. The covariance, which also turns negative at -$6.0 million, reinforces the idea that while one variable may rise, the other’s decline can offset its positive effect.

The total variance is summarized at $73.4 million, which encapsulates the overall financial implications of these changes. This slide serves as a practical guide for executives to grasp how shifts in key variables can affect financial outcomes, emphasizing the importance of variance analysis in strategic decision-making.
