How Statistics Math Problems Look Like & How To Solve Them

Statistics math problems are not only necessary to understand the math question in depth, but it also makes you familiar with real-time things more efficiently. Therefore, it is always important to understand what statistics are and how statistics relate to math. 

Don’t have any knowledge of it? No worries!! I will help you know what exactly statistics math problems are and how they are useful.

Attention

Being a statistics subject student, it is necessary that you must have enough knowledge about statistics questions. Moreover, practice the problems as much as you can. It will help you to clear your doubts and strengthen your conceptual knowledge.

So, let’s check what exactly the statistics math problems are. 

What are the main terminologies used in Statistics?

Just as other subjects, statistics has its own terms and language. This language supports you to understand what actually the problem is, what result requires to come, and methods to describe and analyze the results in the right manner. 

Let’s check some of the main terminologies used in statistics:

A statistic is a sample’s quantitative aspect, which helps in estimating or testing the population parameters. It is of two types (that you have also studied in your schools):
Descriptive statistics represent the result that you conclude at the time of analyzing the data set, like mean, median, mode, standard deviation, and more.Statistical inference is used to draw useful conclusions related to the population—for example, hypothesis test and regression confidence intervals.
The population represents the whole group of people that you need to study. (NOTE: Sample statistics is the subset of this entire group).
A parameter is one of the quantitative characteristics of the given population in which you need to take interest in tests and estimations.
Key point:
What do statistics math problems look like?
Well, before understanding the method to solve statistics math problems, you must consider what these problems look like. 

The problems are mostly given with the details or tables that look like any survey outcomes. As per the table, you need to calculate some of the major terms of statistics, such as mean, median, mode, and so on. But first, you must know all the useful formulas and methods to solve the statistics math problems.

What are some problems with statistics?

There are some of the major problems that can occur when you deal with the statistics data. Therefore, it becomes necessary that you must understand these problems and keep in mind to ignore them.

Sometimes extracting meaning can make a little difference.

When you look for the difference across subgroups and groups for findings, it explains if the percentage difference is large enough to make conclusions or not. 

Therefore, you need to be careful when you deal with the small difference as it can lead to no meaning for making conclusions.

Poor survey designs.

The statistics quality directly depends on the survey quality. But sometimes, we design a survey with free tools and use the survey output for important decision-making. 

That is why you must take care of the survey design to help you make important decisions. It is beneficial if you assign this to an expert who knows how to perform surveys.

Representing meaningless details on a graph.

Sometimes, the graphs can misguide the readers. The graphs like bar graphs can show the bar of large value where the small value might look to be ignored. 

But actually, small values also play a significant role in the statistics data. Therefore, you must use a suitable graph to represent the data.

How to solve statistics math problems?

It has been seen that solving statistics questions needs some strategies. That is why below, I have mentioned important strategies or steps to solve these problems. Let’s find out.

Label each point of the problem or question assigned to you.

Suppose your statistics questions state that A is the normal distribution with a mean value of 5 and the standard deviation (SD) with 1. Then, circle all the numeric terms and write the respective symbols. Like circle 5 and write μ, and so on.

Write what the question demands to find out statistically.

Suppose you assign to calculate the probability of the more than 5 people who joined a competition. Then, write it as “Calculate P(X > 5).”

Also Read

Recall the formula you studied to calculate a similar problem or question while practicing the problem. And connect it with the current statistics math problems.

Suppose your problem topics already have some terms like Standard deviation as 3, mean like 80, and so on. And you need to calculate the probability of x that is less than 80. 

You can see that the z-formula (Z = (Xμ)/σ) can be relevant to solve this kind of problem. Put all the values in the formula. Now you can easily find out the value or the answer to your statistics math problems.

Let’s check a statistics math problem and solve it!!!

Two brothers, James and Caroline, are studying in the same class. The following is the table of their marks they got the whole year in their test.

Calculate in how many subjects Caroline scored better than the brother James. (The mark ranges from 1 to 5.)

Solution

As you can see that we need to calculate the statistical average or mean of each subject that looks like:

Caroline’s average marks:

mathematics: (1+2+3+1+1+5+2)/7 => 15/7 => 2.14 => 2 (approx)

physics: (3+3+1+1+1+2)/6 => 11/6 => 1.83 => 2 (approx)

chemistry: (1+1+1+3+4+1)/6 => 11/6 => 1.83 => 2 (approx)

geography: (2+2+3+1+5+4)/6 => 17/6 => 2.83 => 3 (approx)

James’ average marks:

mathematics: (4+4+1+2+2)/5 =>13/5 => 2.6 => 3 (approx)

physics: (2+2+2+2)/4 => 8/4 => 2

chemistry: (5+5+4+4+3+4+3+3)/8 => 31/8 => 3.88 => 4 (approx)

geography: (1+1+2+1+1+1+2+1)/8 => 10/8 => 1.25 => 1 (approx)

So, Caroline got better marks in one subject (that is geography) than James.

This is how you can understand and solve the statistics math problems in an easy manner.

Practice these statistics math problems on your own!!

The below table has the data of measured heights of all 63 students with its corresponding numbers as:

Calculate the mean, median, mode, variance, and SD of each student’s height.
Correct Answer:
x̄ = 170.8, med = 171, mod = 173, s^2 = 21.87, s = 4.7.

When we weigh 20 of 1Kg tea bags, the following are the measured values that we have noted in kgs:

Calculate the median and the variance of all the calculated weights.
Correct Answer:med(x) = 1, s^2 = 0.0012

Frequently Asked Questions

What is Statistics math with examples?

Statistics consider as the number that shows or describes the sample’s properties. For example, suppose you consider a math class as the sample of all math classes. The mean value of the marks scored in the particular math class in the final exam is the statistics example.

What type of math is used in statistics?

The particular math techniques used in the statistics are as follows:

linear algebra,
differential equation,
mathematical analysis,
stochastic analysis,
measure theory.

Why do we rely on statistics?

With the help of statistical knowledge, you can collect helpful data, develop valuable insights by analyzing the data, and develop useful decisions. Moreover, statistics play an essential role in various scientific discoveries, data-based decisions, and making predictions.
