Question

basic statistics end-of-lesson test
6 find the range of the following data set: 0.5, 0.3, 0.2, 0.9, 0.3, 0.5, 0.2, 0.3
0.4
0.3
0.2
0.7
skip 5/10 complete

Explanation:

Step1: Identify max and min values

The data set is \(0.5, 0.3, 0.2, 0.9, 0.3, 0.5, 0.2, 0.3\). The maximum value (\(max\)) is \(0.9\) and the minimum value (\(min\)) is \(0.2\).

Step2: Calculate the range

The formula for range is \(Range = max - min\). Substituting the values, we get \(Range = 0.9 - 0.2 = 0.7\). Wait, no, wait. Wait, let's re - check the data set. Wait, the data set: let's list all values: \(0.2, 0.2, 0.3, 0.3, 0.3, 0.5, 0.5, 0.9\). So max is \(0.9\), min is \(0.2\). Then \(0.9 - 0.2 = 0.7\)? Wait, but wait, maybe I made a mistake. Wait, no, the range is maximum minus minimum. Wait, but let's check again. Wait, the data set is \(0.5, 0.3, 0.2, 0.9, 0.3, 0.5, 0.2, 0.3\). So the values are: \(0.2, 0.2, 0.3, 0.3, 0.3, 0.5, 0.5, 0.9\). So max is \(0.9\), min is \(0.2\). So \(0.9 - 0.2 = 0.7\). But wait, maybe I misread the data. Wait, the data set: is it \(0.5, 0.3, 0.2, 0.9, 0.3, 0.5, 0.2, 0.3\)? Let's count the numbers: 8 numbers. So max is \(0.9\), min is \(0.2\). So range is \(0.9 - 0.2 = 0.7\). Wait, but the options include 0.7. So that's the answer.

Answer:

\(0.7\)
