Questions: The high-low method of analyzing the cost behavior of a mixed cost uses a(n) square to illustrate cost and volume data relationships.

The answer is: scattergraph

Explanation:

• The high-low method is a technique used to separate the fixed and variable components of a mixed cost. It involves identifying the highest and lowest levels of activity and their associated costs.
• A scattergraph is a type of graph that plots data points on a two-dimensional plane, typically with cost on the vertical axis and volume or activity level on the horizontal axis.
• By using a scattergraph, one can visually assess the relationship between cost and volume data, making it easier to identify patterns or trends and apply the high-low method effectively.
• Other options, such as a line graph or bar chart, are not typically used in the context of the high-low method for analyzing mixed costs.
