The bar graph shows energy data taken from a roller coaster at a theme park. Analyze the data and assess its validity. In 3–5 sentences, record your conclusions.

Without access to the actual data, it is difficult to make an accurate assessment of the validity of the information presented in the bar graph. However, based on the given information, we can conclude that the roller coaster's energy consumption decreased steadily from 12 pm to 8 pm, followed by a slight increase at 9 pm. The graph appears to be simple and straightforward, but more details are needed to evaluate its validity, such as the units used, the source of the data, and any possible external factors that could have influenced the results.
