between the rate of photosynthesis and the wavelength of the light used‚ we can see a relationship between the colour of the leaf‚ the rate of photosynthesis and the colour of light used. With colours that are similar to the colour of the leaf such as green and yellow‚ lower rates of photosynthesis were identified while colours that were opposite to the colour of the leaf gave the highest rate of photosynthesis such as red. All of the results compared to the control showed a lower rate of photosynthesis

rearranging data is through the stem-and-leaf plot. A stem-and-leaf plot is a display that organizes a set of data to show both its shape and its distribution. Each data value is split into a “stem” and “leaf”. The leaf is usually the last digit of the number‚ and the other digits to the left of the leaf form the stem. Example 2: The stem-and-leaf plot for the ages of farmer borrowers interviewed: 29‚ 37‚ 32‚ 46‚ 45‚ 45‚ 54‚ 51‚ 55‚ 55‚ 55‚ and 60. Stem Leaf 2 9 3 72
