Scatter Graphs
Mathematics · Data & Statistics · representational
Plot bivariate data on a scatter graph with correctly labelled axes and appropriate scales; describe the correlation (positive, negative, none) and draw an estimated line of best fit where appropriate
What mastery looks like
- 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
Check your understanding
If Scatter Graphs 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?
