Matched Pair
Stats: How do you know if question is asking for matched pair?
Stats: How do you know if question is asking for matched pair or independent samples of 2 population?
If the sample items remains the same it is a case of matched pair.
For ex. Ten students A B C D E F G H I J took special coaching.
If the effectiveness of the coaching is to be judged, it is desirable to test the significance of difference of mean of marks secured BEFORE coaching and mean of marks secured AFTER coaching.
In this example the students remain the same whereas their marks before and after coaching are considered.
Normally the words BEFORE and AFTER will be there in the question
If it is not a case of matched pair , it will be a case of independent samples. In this case two separate samples of same size or different size will be selected.

Matched $9.99 Cassia has always trusted the Society to make the right choices for her: what to read, what to watch, what to believe. So when Xander's face appears on-screen at her Matching ceremony, Cassia knows he is her ideal mate . . . until she sees Ky Markham's face flash for an instant before the screen fades to black. The Society tells her it's a glitch, a rare malfunction, and that she should focus on the happy life she's destined to lead with Xander. But Cassia can't stop thinking about Ky, and as they slowly fall in love, Cassia begins to doubt the Society's infallibility and is faced with an impossible choice: between Xander and Ky, between the only life she's known and a path that no one else has dared to follow. |
