True or false? When presenting your data on a bar chart, it's effective to alter your axes so your audience only needs to see the necessary information.

False. Altering axes to show only "necessary" information can be misleading and distort the true representation of the data. For example, starting a y-axis at a value other than zero can exaggerate small differences between bars, making them appear more significant than they are. This practice can manipulate perceptions rather than provide an accurate, unbiased view. While it's important to focus on relevant data, maintaining accurate scales is crucial for data integrity and effective communication.
