Here are some practice assessments you can look at:

Bay Leaf Investigation:
 * Question**: is there a relationship between the length and the width of bay leaves?
 * Plan:** Each person in our class was given a bay leaf to measure then record on a table. There were 29 in total measured. We measured them in mm using a 30cm ruler.
 * How did we manage variations:** We measured from the top of the leaf to the bottom, not including the stem at all. We measure in a straight line, not the curve of the leaf (if any). For the width we measured the widest part.

Now draw a table and enter the data:
 * length (mm) || width (mm) ||
 * 90 || 32 ||
 * 80 || 20 ||
 * 60 || 30 ||
 * 80 || 27 ||
 * 95 || 27 ||
 * 90 || 27 ||
 * 95 || 27 ||
 * 86 || 24 ||
 * 80 || 21 ||
 * 50 || 15 ||
 * 74 || 20 ||
 * 70 || 21 ||
 * 67 || 20 ||
 * 88 || 28 ||
 * 90 || 25 ||
 * 75 || 20 ||
 * 103 || 26 ||
 * 87 || 16 ||
 * 83 || 24 ||
 * 68 || 24 ||
 * 70 || 24 ||
 * 95 || 28 ||
 * 86 || 27 ||
 * 104 || 31 ||
 * 72 || 18 ||
 * 88 || 23 ||
 * 98 || 32 ||
 * 65 || 18 ||
 * 75 || 25 ||

Then draw your scatter graph (correct scales: eg, height (mm); title) see here for data and scatter graph/trendline

There is an outlier; which I know is an outlier because it is too far off the trendline and further investigation is required
 * Conclusion**: I discovered that the longer the length of the bay leaf, the …………… the width tends to be. My graph shows a weak/moderate/strong, positive/negative graph which can be seen on my scatter graph as the data is close/not close to the trend line
