Zoe decided to measure the hand length of each of her classmates. First she marked a line across each student's wrist and lined up a ruler from this mark to the top of the middle finger to measure the length. Then she recorded the measurements in the table below. Marla did this the same way for each classmate, and then Zoe used this ruler to measure each straight line and record the data below. This data is invalid. What is the most likely reason why it is invalid? The ruler is marked in centimeters, but Zoe recorded data in inches. The range of lengths is too wide, so Zoe must have misread the ruler. Marla’s complicated measuring procedure was overly confusing. Marla could have been inconsistent while drawing outlines of fingers. Mark this and return

Answer:
The ruler is marked in centimeters, but Zoe recorded data on the ruler.
Explanation:
Because the ruler is marked in centimeters, but Zoe recorded data in inches, her data is invalid. The ruler is used to measure short distances. The ruler measures in centimeters rather than inches. Zoe cannot record the data in inches because the ruler is graduated in centimeters rather than inches. As a result, the information is invalid.
