What is Statistics in Math?
Mathematics and Statistics share a common set of principles that help in the analysis of data. They involve logical reasoning, critical analysis and quantitative procedures. Maths and statistics both play an important role in a number of fields including data science, finance, business, economics and many more.

What is a Data Sampling Technique?
In statistics, sampling is the process of collecting and compiling data from a representative sample. It is a type of statistical technique that allows for more efficient and effective analyses, especially in cases where the entire population cannot be observed in its entirety.
What is the Difference Between Quantitative and Nominal Level Measurements?
One major difference between quantitative and nominal levels of measurement is that non-numerical descriptors such as quality, strength, and length are not ranked. For example, a car is considered a quantitative descriptor if it has a number of miles on the odometer. Nominal level measurements on the other hand are based more on qualitative qualities such as speed and height.
What is the Definition of a Statistical Measure?
A statistical measure is a numerical value that describes the probability of an event occurring. This can be expressed in terms of percentages or a range of values (e.g., a chance of 0.5 for heads or tails).
What is the difference between a Continuous and a Discrete Quantitative Variable?
Discrete quantitative variables are usually measured into decimals. This type of variable has limitations in statistics compared to continuous ones, as there are gaps between possible values. For example, the number of points scored in a football game is a discrete variable.
What is the Definition of Statistical Dispersion?
Statistical dispersion is the measure of how closely the values of a set of data cluster around the mean. This is an important statistic because it helps in determining how much variance there is in the data. Similarly, standard deviation is another measure of statistical dispersion. The standard deviation is a square sum of the variances.
What is the Meaning of a Graph in Statistics?
In statistics, a graph is a tool used to display the data in a format that makes it easier for analyzing. It can also be used to highlight trends in the data. It is a type of graph that can show the average, maximum and minimum values of a particular variable over time.
What is the Difference between a Statistical Variable and a Nominal One?
A statistical variable is a quantity that has a specific meaning. It can be a numerical descriptor or it can be a quality that is ranked.
The first type of a statistical variable is called a quantitative variable. This type of information is rooted in numbers and only has weight when the value is above a non-numerical descriptor. In the example above, the number 60,000 holds no value unless it is understood that the total number of miles driven is 60,000.
There are other types of statistics that include descriptive and inferential. The former helps in the description of the data, while the latter involves predicting and making inferences from the data. These methods are very useful in a number of industries, from agriculture to the media and even government agencies. The most popular careers for a statistics degree are Data Analyst, Market Research, Financial Analyst, Cost Estimator, Banking & Insurance, Health and Medicine Research, Behavioural Sciences, Industry & Operation Management, Academics etc.
