Scatter graph worksheets.
Keep each pair together.

Plot eight numerical pairs in each of four fictional datasets. Compare rising, falling and less clear patterns while keeping association separate from causation.

Use the student pack for an attempt, then compare the separate reference or worked answer. Every case is original. All PDF and editable SVG resources are free without signup; each collection pack repeats its individual sheets in the same order.

The examples and datasets are made for these worksheets. They are not measured classroom results, published textbook questions or evidence about real people. Axis values and the supplied data determine the answers; paper measurements do not replace those numbers.

SP01: Rising paired values

The table gives one worked case so you can check the method. The separate answer files contain the completed plots and results for every case. Table order can change without changing the scatter, as long as each x and y stay paired.

1. Plot the pairs without changing their partners Each ordered pair has two values from the same fictional observation. Place the first value on the horizontal Input setting axis and the second on the vertical Recorded score axis. Both axes run from 0 to 10 in single-unit steps. SP01 begins with (1,2), followed by (2,3); do not sort the two columns independently. The student file supplies the labeled axes and the eight-pair list. Keep the reference and answer packs aside for your first attempt, then compare each dot with the same pair in the list.
2. Verifying Axis Labels and Units Before plotting, confirm that the horizontal axis is labeled Input setting in units and the vertical axis is labeled Recorded score in units. These labels apply to all four paired-data construction tasks. Since answers are determined by axis units and plotting rather than physical ruler measurement, precise alignment with these listed coordinates is essential. Check that the scale accommodates the eight observations in each case without truncation. The data points are fictional and not copied from publishers. Ensure the axes are clearly visible on your screen or printed page to accurately interpret the positive, negative, or no clear linear association trends presented in the exercises.
3. Plotting Points Without Connecting Lines Plot each pair of x and y values exactly once for the eight observations in your selected case. Keep all points unconnected, as no best-fit line or causal calculation is required for these exercises. For the case with a rising pattern, note the unusual low point at coordinates five and two. For the case with no clear straight-line trend, observe the scattered distribution. Remember that a lack of clear linear association does not prove statistical independence. A light label can help identify an unusual point. The visual representation relies solely on the listed coordinates provided in the original fictional datasets, ensuring consistency across all student and worked answer versions.

Choose the Letter or A4 file that matches your paper. Actual size / 100% preserves the designed layout; a different uniform print scale changes physical lengths but does not change the listed numbers or the arithmetic. Keep the whole chart and all labels inside the printable area. A ruler can help draw straight segments, but calculate from the stated numerical scale.
