Janette is growing tomato seedlings. She just took measurements of her seedlings, and her are her data, in centimeters.

Question

4,3.5,6.7.2,5,6.1,3.6,7.1,3,3.2
What are the mean and median seedling heights?

Answer 1

To find the mean, we add up all the measurements and then divide by the number of measurements:

Mean = (4 + 3.5 + 6.7 + 2 + 5 + 6.1 + 3.6 + 7.1 + 3 + 3.2) / 10 = 4.94 cm

To find the median, we first need to arrange the measurements in ascending order:
2, 3, 3.2, 3.5, 3.6, 4, 5, 6.1, 6.7, 7.1

Since there are 10 measurements, the median is the average of the 5th and 6th measurements:

Median = (3.6 + 4) / 2 = 3.8 cm

Therefore, the mean height of Janette's tomato seedlings is 4.94 cm and the median height is 3.8 cm.
