Check understanding
- Plot 10 data points on a scatter graph with correct axis labels and a consistent scale
- Draw a line of best fit by eye, ensuring roughly equal numbers of points above and below
- Use the line of best fit to estimate a y-value for a given x-value within the data range
“If your child has data comparing hours of sleep and test scores for 10 students, can they plot the points on a scatter graph, draw a line of best fit, and use it to predict a score for someone who slept 7 hours?”
