Janette is growing tomato seedlings. She just took measurements of her seedlings, and here are her data, in centimeters.
4, 3.5, 6, 7.2, 5, 6.1, 3.6, 7.1, 3, 3.2
What are the mean and median seedling heights?
(1 point)
Mean=
cm. Median=
cm.
Mean = (4 + 3.5 + 6 + 7.2 + 5 + 6.1 + 3.6 + 7.1 + 3 + 3.2) / 10
Mean = 48.7 / 10
Mean = 4.87 cm
To find the median, first, arrange the data in ascending order:
3, 3.2, 3.5, 3.6, 4, 5, 6, 6.1, 7.1, 7.2
Since there are an even number of data points (10), the median is the average of the two middle numbers:
Median = (5 + 6) / 2
Median = 5.5 cm
Therefore, the mean seedling height is 4.87 cm and the median seedling height is 5.5 cm.
