Answer:
Q₂ = 10
Step-by-step explanation:
Given data set: 3, 9, 12, 4, 6, 40, 25, 14, 10
Q₂ is the median (the middle value) of the <u>given data set</u> when the data set is <u>ordered</u> from <u>smallest to largest</u>.
<u>Order the values</u> in the data set:
3, 4, 6, 9, <u>10</u>, 12, 14, 25, 40
As the number of values is <u>odd</u>, the middle value is the 5th value.
Therefore, the median (Q₂) of the given data set is 10.
If the number of data values is <u>even</u>, and therefore there are <u>two middle values</u>, the median is <u>halfway</u> between them.
