Figure 1
A vertical dot plot compares percentile points for different student groups based on the number of investigations. The horizontal axis represents three student groups: 8th grade students, female, black, and Hispanic students, and ELL students. The vertical axis represents percentile points ranging from 50 to 78. Each dot represents a percentile point for a specific number of investigations, with colors indicating the number of investigations: blue for 1 investigation, green for 2 investigations, yellow for 3 investigations, and orange for 4 investigations. For 8th grade students, percentile points range from around 52 to 58, with higher investigations generally corresponding to higher percentile points. For female, black, and Hispanic students, percentile points also range from around 52 to 58, showing a similar pattern. For ELL students, percentile points range from around 50 to 78, with a significant increase in percentile points as the number of investigations increases.More investigations lead to higher scores on the science assessment
