Sometimes changes in percentage can b. Misleadingly suggest improving performance. This statement addresses the concept that the representation of data, such as percentages in graphs, can be manipulated to create an impression of improvement where there might be none.

By altering the scales on the axes, the time frame, or the context of the data, these graphs can give vastly different impressions of performance or trends.
Data visualization is a powerful tool and, when used responsibly, can accurately convey complex information. However, if not used correctly, it can be a means to mislead or deceive the viewer. This is why critical thinking and a careful examination of graphs and charts are important when interpreting changes in data.
