Question

Geometric mean and harmonic mean for values 3, -11, 0, 63, -14, 100 are​

Answer 1

Answer:

.The geometric mean (G.M.) and the harmonic mean (H.M.) forms an important measure of the central tendency of data. They tell us about the central value of the data about which all the set of values of data lies. Suppose we have a huge data set and we want to know about the central tendency of this data set.

We have so many ways by which we can do so. But what if the data sets are fluctuating or we need to add or remove some of the data value? Calculating the average value or the central value will be a tiresome and troublesome task. So, we use geometric and harmonic means as our rescuer.

Answer 2

Answer: G.M.=0 and H.M.=0

Step-by-step explanation:

• To calculate the Geometric mean we multiply all the values and take its $n^{th}$ root.
• G.M.=$\sqrt{3*(-11)*0*63*(-14)*100}$

              =0

• So, the Geometric mean is 0.
• To calculate the Harmonic mean we have to divide the numver of terms N by the sum of the reciprocals of the terms.
• H.M.=$\frac{6}{\frac{1}{3}- \frac{1}{11}+\frac{1}{0}+ \frac{1}{63} -\frac{1}{14}+ \frac{1}{100} }$

               =0

• Hence, harmonic mean is also 0.
