Question

sara is practicing speed pole climbing. the data show her times in seconds. 16 17.5 17 18 16.5 17 20 saras range = 4 seconds saras iqr = 1.5 seconds christa is also practicing her speed pole climbing. the iqr of her practice times is 5 seconds. complete the statement. saras iqr is? than christas iqr. that means that saras practice times are? variable than christas practice times.

Explanation:

Step1: Compare IQR values

Sara's IQR is \(1.5\) seconds and Christa's IQR is \(5\) seconds. Since \(1.5<5\), Sara's IQR is smaller.

Step2: Understand the meaning of IQR

The inter - quartile range (IQR) measures the spread or variability of a data set. A smaller IQR means less variability.

Answer:

Sara's IQR is smaller than Christa's IQR. That means that Sara's practice times are less variable than Christa's practice times.
