Answer:

B. 2.25

Read Explanation:

ആരോഹണ ക്രമത്തിൽ എഴുതുമ്പോൾ :

1, 2, 3 , 4, 5, 6, 7, 9

Q1=(n+14)thvalueQ_1 = (\frac{n+1}{4})^{th} value

Q1=94thvalue=2.25thvalueQ_1 = \frac{9}{4}^{th} value = 2.25^{th} value

Q1=2nd+0.25(3rd2nd)Q_1 = 2^{nd} + 0.25 (3^{rd}-2^{nd})

Q1=2+0.25(32)=2.25Q_1 = 2 + 0.25 (3-2) = 2.25

Q3=3×(n+14)thvalueQ_3 = 3 \times (\frac{n+1}{4})^{th} value

Q3=3×2.25=6.75thvalueQ_3 = 3 \times 2.25 = 6.75^{th} value

Q3=6th+0.75(7th6th)Q_3 = 6^{th} + 0.75(7^{th} - 6^{th})

Q3=6+0.75(76)Q_3 = 6 + 0.75(7 -6)

Q3=6.75Q_3 = 6.75

ചതുരംശ വ്യതിയാനം QD = Q3Q12\frac{Q3 - Q1}{2}

QD=6.752.252QD = \frac{6.75 - 2.25}{2}

QD=2.25QD = 2.25
