Determine whether the data are from discrete data or continuous data set.

Criminal ForensicsWhen studying the relationship between lengths of feet and heights so that footprint evidence at a crime scene can be used to estimate the height of the suspect, a researcher records the exact lengths of feet from a large sample of random subjects.

Short Answer

Expert verified

Foot lengths measured of suspects at a crime scene form a continuous data set.

Step by step solution

01

Given information

The lengths of the feet of suspects are recorded at a crime scene to estimate their height.

02

Discrete and continuous data

  • Discrete data:

Countable fixed values that have no units form discrete data. For example, the number of food orders at a café, the number of chapters in a book, etc.

  • Continuous data:

Uncountable real-valued data that has units form continuous data. For example, the cost of a laptop, the width of a leaf, etc.

03

Classification of data

As the lengths of feet are measured in centimeters and can take a decimal value, they are acontinuous data set.
