------------------------------------------------ Courtney is making regular observations of the growth rate of kudzu vines 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 is shown below. What issue with her data does Courtney need to resolve?

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

A) Inconsistent units of measure
B) Insufficient amount of data
C) Duration of the study
D) Number of samples

When taking data such as measurements, it is very important that the results are reported in the same unit of measure. Failure to do so will eventually affect your analysed result.

Answer:

A) Inconsistent units of measure

Explanation:

Since Courtney measured the same variable in all the tagged tendrils, the unit of measurement is supposed to be the same. Before any further processing or analysis of the data, she will need to use the appropriate conversion factors to convert all the variates to the same unit.

The research lasted for a whole year and data were collected weekly, the issue of insufficient data or duration of study does not arise in this case. Also since, the size of study population was not indicated, it will be be difficult to point out the sample size as an issue.

The correct option is A.
