Question

  1. researchers studied how the stress levels of participants differ across three different therapy types: cognitive - behavioral therapy (cbt), mindfulness meditation, and group therapy. the data are visualized in the plot on the right. what kind of plot was used by the researchers? a) histogram b) box - and - whisker plot c) box plot d) dot plot 16. for the mindfulness therapy type group in the experiment above, the researchers computed the following statistics: minimum = 18.5; q1 = 32.5; median = 39.5; q3 = 46.5; maximum = 62.5. based on the information, compute interquartile range (iqr). a) 14 b) 46 c) 7 d) 49.5

Explanation:

Step1: Recall IQR formula

The inter - quartile range (IQR) is calculated as $IQR = Q3 - Q1$.

Step2: Identify Q1 and Q3 values

Given that $Q1 = 32.5$ and $Q3 = 46.5$.

Step3: Calculate IQR

$IQR=46.5 - 32.5=\frac{46.5 - 32.5}{1}=14$.

Answer:
