# What is Mean (3, 6, 9, 12, 15, . . . . , 24, 27)?

getcalc.com's Mean (μ) calculator to find what is the mean, mode & median for dataset 3, 6, 9, 12, 15, 18, 21, 24 & 27 to measure & summarize the center point or common behavior, repeated occurrence & central tendency of collection of sample or population data in *probability *& statistical experiments. 15 is the mean, 15 is the median and no mode is available for above dataset.

## How to Find Mean for 3, 6, 9, 12, 15, . . . . , 24 & 27?

The below workout with step by step work help grade school students or learners to understand how to find what is the mean or *average* for data set 3, 6, 9, 12, 15, 18, 21, 24 and 27 to measure or locate the center point of sample or population data which involved in the statistical survey or experiment, to draw conclusions of sample or population data characteristics.

__Mean :__

step 1 Address the formula, input parameters & values.

Formula:*µ* =
n
∑
i = 0
X_{i}n

Input parameters & values

x_{1} = 3; x_{2} = 6, . . . . , x_{9} = 27

number of elements n = 9

Find sample or population mean for 3, 6, 9, 12, 15, 18, 21, 24 & 27

step 2 Find the sum for dataset 3, 6, 9, 12, 15, . . . . , 24 & 27

*µ* =
n
∑
i = 0
X_{i}n

= (3 + 6 + 9 + . . . . + 27)/9

step 3 Divide the sum by number of elements of sample or population

= 135/9

= 15

Mean (3, 6, 9, 12, 15, . . . . , 24, 27) = 15

15 is the mean for dataset 3, 6, 9, 12, 15, . . . . , 24 & 27 from which the *standard deviation* about to be measured to estimate the common variation of the sample or population dataset from its central location.__Median :__

step 1 To find Median, arrange the data set values in ascending order

Data set in ascending order : 3, 6, 9, 12, 15, 18, 21, 24, 27

step 2Since the total number of elements in the dataset is 9 (ODD number), the 5^{th} element 15 is the median for the above data set.

Median = 15

__Mode :__

step 1 To find Mode, check for maximum repeated elements in the asending ordered dataset 3, 6, 9, 12, 15, 18, 21, 24, 27

No mode available for the above dataset
