Question 2 (1 point)

Elena collects 112 specimens of beetle and records their lengths for an ecology research project. When she

returns to the laboratory, Elena finds that she incorrectly recorded one of lengths of the beetles as 122

centimeters (about 4 feet). What should she do with the outlier, 122 centimeters, when she analyzes her data?

A.

She should exchange the recording error with the average length from her other measurements.

B. She should take the 4 foot long beetle to Guinness Book of Records

C.She should go back and remeasure all of her specimens again to find the error. If she can't do this, she should eliminate the

outlier from her analysis, because this is an error in recording.

Answer 1

The correct option is;

C. She should go back and remeasure all of her specimens again to find the error. If she can't do this, she should eliminate the outlier from the analysis, because this is an error in recording

Explanation:

In order to minimize error in measurement, some valuable steps includes;

1) Perform a double check on all measurements to ensure that the measurements recorded are accurate

2) Ensure proper training before taking measurements

3) Measurements should only be taken under controlled conditions

4) Separate the entire population into smaller groups for proper recording

5) Have a second observer double check the records
