1.	For a normal distribution having mean 10 and standard deviation 6, estimate the value of quartile deviation.
Answer» Here, µ = 10; σ = 6 Estimated value of quartile deviation: In normal distribution, Quartile deviation ≈ \(\frac{2}{3}\) σ Putting, σ = 6 Quartile deviation ≈ \(\frac{2}{3}\) ≈ = 4 Hence, the estimated value of quartile deviation obtained is 4.

For a normal distribution having mean 10 and standard deviation 6, estimate the value of quartile deviation.

Answer»

Here, µ = 10; σ = 6

Estimated value of quartile deviation:
In normal distribution, Quartile deviation ≈ \(\frac{2}{3}\) σ
Putting, σ = 6
Quartile deviation ≈ \(\frac{2}{3}\) ≈ = 4
Hence, the estimated value of quartile deviation obtained is 4.
