Courtney is making regular observations of the growth rate of kudzu vines on a ditch in her neighborhood. She isolated and tagged five tendrils of the vine, and takes weekly cumulative measurements for a year. A portion of her results are shown below. What issue with her data does Courtney need to resolve?

Hello. You forgot the results of Courtney's observations. The observations are:

"Tendril # Week 1 Week 3 Week 6

1 1.2 cm 5.9 in 1.2 ft

2 2.0 cm 4.8 in 0.98 ft

3 0.8 cm 3.2 in 0.55 ft

4 0.2 cm 1.6 in 0.35 ft

5 1.5 cm 4.3 in 1.01 ft"

Curtney's data show inconsistent units of measure.

Explanation:

Measurement units are ways of representing great physics such as speed, size, time, quantity, weight, among others. These units serve to quantify the matter and allow observations to be made.

It is important to note that the same units of measurement must be evaluated in the same experiment. For example, if we want to evaluate how much a plant can grow in 3 weeks, we have to evaluate the same unit of measure each week. If in the first week we evaluate the growth in centimeters, we have to evaluate the growth in the next weeks also in centimeters.

Courtney did not do this, and assessed the growth of the plants each week with different units of measure, which left her data inconsistent.
