find the mean of×+3×+5×+7×+9×+11
Answers
Step-by-step explanation:
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 1, 3, 5, 7, 9 and 11 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
Xi
n
Input parameters & values
x1 = 1; x2 = 3, . . . . , x6 = 11
number of elements n = 6
Find sample or population mean for 1, 3, 5, 7, 9 & 11
step 2 Find the sum for dataset 1, 3, 5, 7, 9 & 11
µ =
n
∑
i = 0
Xi
n
=(1 + 3 + 5 + . . . . + 11)
6
step 3 Divide the sum by number of elements of sample or population
=36
6
= 6
Mean (1, 3, 5, 7, 9, 11) = 6
6 is the mean for dataset 1, 3, 5, 7, 9 & 11 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 : 1, 3, 5, 7, 9, 11
step 2Since the total number of elements in the dataset is 6 (EVEN number), the median is the average of 3rd and 4th elements (two middle numbers) for the above dataset.
Therefore,
5 + 7
2
= 6
Median = 6
Mode :
step 1 To find Mode, check for maximum repeated elements in the asending ordered dataset 1, 3, 5, 7, 9, 11
No mode available for the above dataset
