Biased Problems Math

Introduction to biased problems in math:

Normally biased problems in math are nothing but a question wondered the answers are favored over others such a way. And the main thing in biased math problems are it will make some assumptions. These assumptions on a biased problems may or may not be true.

Example:

Do you want t eat pizza or burger? This is an unfair question, because it favors pizza over burger.

Let us see some examples for biased problems in math.

Examples foe biased problems in math:


Example 1:

If the following question is a biased then say the answer as 0 or 1. Where yes mean 1 and no mean 0.

Do you like math subject?

Solution:

The given question is Do you like math subject?

The answer is 0. Because here it won’t take any assumption or I didn’t take any answers over another answer. So it is an unbiased question.

Example 2:

A survey among the importance of the elder’s health care conducted. The percentage of the health care and age of the elders is given. These percentage and age gives the sample. From this find which sample is a biased one.

Sample 1:

Percentage (%)    28    25    22    23
Age limit    30 - 45    46 - 50    50 - 60    61 - 80
Sample 2:

Percentage (%)    32    28    34    6
Age limit    30 - 45    46 - 50    50 - 60    61 - 80
Sample 3:

Percentage (%)    18    19    25    26
Age limit    30 - 45    46 - 50    50 - 60    61 - 80
Sample 4:

Percentage (%)    10    15    22    20
Age limit    30 - 45    46 - 50    50 - 60    61 - 80

Solution:


From the above we understand a sample is nothing but a population sample.

When a population survey has to take mean we have to take the population sample we have to study.

Here the percentage of sample which is above 80 is 6 %. And it does not represent the opinions about the previous elders. So sample 2 is a biased one.
