<h2>Given :-</h2>
- Observation
- 2,5, 3,3,0, 18, 5, 7, 11, 15, 1, 13, 0,8,0
<h2>To Find :-</h2>
<h2>Solution :-</h2>
As we know that
- Mean = 2 + 5 + 3 + 3 + 0 + 18 + 5 + 7 + 11 + 15 + 1 + 13 +0 8 + 0/15
- Mean = 91/15
- Mean = 6.04
<h3>Now,</h3>
- Median = n + 1/2
- Median = 15 + 1/2
- Median = 16/2
- Median = 8th term
<h3>Now,</h3>
- 0 appears most (3) times.
- Mode = 0
<h2>Conclusion :-</h2>
<h3>Mean = 6.04</h3><h3>Median = 5</h3><h3>Mode = 0</h3>
