Data on daily participation in high school physical education (PE) classes from 1991 to 2001 is not readily available in a single, easily accessible source. Studies on PE participation often focus on specific years, states, or school districts rather than providing a consistent national trend over that entire decade. You'd likely need to consult numerous research papers and government reports from that period to piece together a picture of participation rates.
Furthermore, the data would likely show a *decrease* in daily PE participation during that time frame. The trend throughout the 1990s and into the 2000s was a decline in required PE and overall time dedicated to physical activity in schools due to factors like budget cuts, increased academic pressure, and a focus on standardized testing. However, without specific research, any statement about the precise numbers would be speculative.
