Sample Research Questions
Introduction to sample research questions:
The concept of sample research is formed by the population sampling. The items are chooses from the set of inhabitants through randomly. The sample research is also the part of statistics in mathematics.The word sample represents a small quantity. The sampling is also one of the statistics distributions. The sample research questions explain the fundamental concepts of samples. These research questions are containing the mean of sample, median of sample, mode of sample.
Sample Research Questions-definition:
Sampling is the method of choosing from a people of attention. The sampling is also contains continuous signal to a discrete signal. The sample able to refers the set of values. The samples can also explain the mean, median and mode.
Terms:
Term 1: Mean.
Term 2: Median.
Term 3: Mode.

Sample Research Questions-examples:
Term 1: Mean.
Problem 1:
Research the answer for sample mean questions. Where the samples are 20,30,40,50,60,70.Find the mean value.
Solution:
The formula for mean = (Addition of all sample values ) /( Total number of sample values).
= (20+30+40+50+60+70) / 6.
=270 / 6.
= 45.
So the mean value = 45.
Problem 2:
Research the answer for sample mean questions. Where the samples are 25,35,45,55,65.Find the mean value.
Solution:
The formula for mean = (Addition of all sample values) / (Total number of sample values).
= (25+35+45+55+65) / 5.
=225 /5.
= 45.
So the mean value of given sample is 45.
Term 2: Median
Problem 1:
Research the answer for sample median questions. Where the samples are 100,50,70,30,10,60,20,80,90,40.Find the median
Solution:
Step 1: For finding the median, first sort the values.
10,20,30,40,50,60,70,80,90,100.
Step 2: find two middle values. To find the median take average of that both values.
Median = 50+60 /2.
= 110 /2.
= 55.
Thus the median is 55.
Problem 2:
Research the answer for sample median questions. Where the samples are 25,45,75,95,5,35,65,15,85,55.Find the median
Solution:
Step 1: For finding the median, first sort the values.
5,15,25,35,45,55,65,75,85,95.
Step 2: find two middle values. To find the median take average of that both values.
Median = 45+55 /2.
= 100 /2.
= 50.
Thus the median is 50.
Term 3: Mode
Problem 1:
Research the answer for sample median questions. Where the samples are 12,23,87,45,67,87.
Solution:
The mode is defined as; to choosing the highest frequency from the set of data is called as mode.
From our problem, we have the highest value as 87 and also it is presented as twice from our data.
So, the mode is 87.
Problem 2:
Research the answer for sample median questions. Where the samples are 21,32,98,54,76,98.
Solution:
The mode is defined as; to choosing the highest frequency from the set of data is called as mode.
From our problem, we have the highest value as 98 and also it is presented as twice from our data.
So, the mode is 98.
