Question

Explain the terms arithmetic mean, median, mode, geometric mean and harmonic mean.

Answer 1

Harmonic Mean:

The harmonic mean is a type of numerical average. It is calculated by dividing the number of observations by the reciprocal of each number in the series. Thus, the harmonic mean is the reciprocal of the arithmetic mean of the reciprocals.

Geometric Mean:

Geometric Means. The term of a geometric progression or sequence, which are between two terms of the sequence are called geometric means between the two terms.

Mean:

Express in terms of. It means to express the quantity you're finding in terms of , the variable.

Mode:

The mode is a statistical term that refers to the most frequently occurring number found in a set of numbers.

Median:

The "middle" of a sorted list of numbers.  

Answer 2

Answer:

Explanation:

Arithmetic mean

The arithmetic mean is defined as the ratio of sum of all the observations to  the total number of observations.

Median

The median is the mid-value of the given data after arranging it in a particular order ascending or descending.

Mode

The number which occurs most frequently in the given data is known as the mode.

Geometric Mean

The geometric mean is defined as the nth root of the product of the n numbers of observations.

Harmonic Mean

The harmonic mean is defined as the reciprocal of the average of reciprocals of the given observations.
