Question

(I) find the range for the following observations: 65,70,82,59,81,76,67,60,65 and 50.

what do you mean by a measure of central tendency ? mention different type of averages .

​

Answer 1

Answer:your answer is 32

Step-by-step explanation:

Range=the largest number in given data-the smallest number in given data.

Here, largest number is 82

And smallest number is 50

So, 82-50=32.

Hope this is useful to you

Answer 2

Range would be 32.

Given

• observations

To find

• range
• measure of central tendency
• different type of averages .

solution

we are provided with an observation and are asked to determine the range of the observation

the range of the observation is defined as the largest observation minus the smallest .

Therefore range of the given observation would be,

R = 82 - 50

or, R = 32

now we are asked to define measure of Central tendency.

the measures of Central tendencies are the values of an observation that correctly predicts the central value of the observation or in a sense that the whole essence of the observation is assumed to be concentrated in the central value.

Central tendency include Arithmetic mean, Meadian and Mode.

Although, the term average points straight to Arithmetic mean it may also signify other central value measures such as median and mode but it is not usually used in such a sense.

The arithmetic mean may further be divided as simple arithmetic mean geometric mean harmonic mean. which may further be divided as weighted arithmetic mean or simplest arithmetic mean for each case.
