A student investigated the number of stomata on the lower epidermis of leaves taken from plants of the same species growing in two different environments.
Using a light microscope, the student counted the number of stomata in several fields of view. The results for one leaf are shown in the table:
| Field of view | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
|---|---|---|---|---|---|---|---|
| Number of stomata | 14 | 16 | 14 | 21 | 15 | 14 | 18 |
Which option gives the correct values for mean, median and mode?
Mean = 141414, median = 151515, mode = 161616
Mean = 151515, median = 161616, mode = 141414
Mean = 161616, median = 151515, mode = 141414
Mean = 161616, median = 141414, mode = 151515
