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.
To find the mean, add all the seedling heights together and divide by the total number of measurements:
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 measurements in ascending order:
3, 3.2, 3.5, 3.6, 4, 5, 6, 6.1, 7.1, 7.2
Since there are 10 measurements, the median will be the average of the 5th and 6th measurements:
Median = (4 + 5) / 2
Median = 4.5 cm
Therefore, the mean seedling height is 4.87 cm and the median seedling height is 4.5 cm.
