Statistical analysis is a key element of the highly important tool called data science. It helps in conducting a technical analysis of a collection of data by a mathematical approach. Statistics help analysts to understand the viability and significance of a certain result and whether or not it is statistically significant. Visual representation of statistical analysis like bar graphs, pie charts offer specific and informative depictions of data.

Statistics is a notable domain of mathematical analysis that has varying significance in almost every subject matter. It is a collection of various topics that has major importance in diverse areas. Each of these subject matters is essential to build a thorough knowledge of the subject. Moreover, it is necessary for students to bear meticulous skills in mathematical calculations to score a decent result in statistics.

Statistics homework assignments vary according to their level of difficulty. They might be from various important topics like probability, correlation, central tendency, and so on. Developing a detailed understanding of each of these topics can help score a better grade in statistics exam. Religious practice and necessary assistance from experienced tutors are of huge help when it comes to covering the vast syllabus of a monumental subject like statistics.

Statistics and its categories

Statistics offers several tools that assist in calculation and forecasting to simplify the process of data analysis. It is rigorously implemented in diverse fields that include academics, business houses, government agencies, and so on.

Based on the characteristics and availability of data, statistics can be distinguished into two major categories. They are-

1. Qualitative data

In the case of qualitative analysis, the data for statistical interpretation is available in the natural language form and not as a numerical description.

• Quantitative data

On contrary to qualitative data, quantitative data analysis is strictly based on numerical data.

Both the categories of statistical interpretation of data are a fundamental requirement to facilitate data forecast, representation, and optimal analysis of information.

A subject matter with such varied significance in almost every other academic discipline is extensively taught in nearly all academic institutions. Students are subjected to details of this subject to develop a strong foundation that will ultimately help in building their analytic skills.

The ability to accurate analysis also helps in arriving at statistically viable conclusions which is now a must in research, businesses, and all other professional fields. Students can turn to websites to obtain ample materials on various data types.

Central tendency- the fundamental element of Statistics

Statistical analysis is conducted on specific or non-specific data sets obtained from distinct surveys, investigations, and studies. Several statistical tools are frequently recruited to deduce and interpret the collected information.

Central tendency forms the core of statistical analysis and is a quintessential tool required for any data interpretation. It can be defined as the value or position in a particular data set around which the other values tend to cluster or accumulate. It provides a descriptive review of the set of data under study via a distinct value that represents the center of the numerical distribution.

One major disadvantage of central tendency is that it is incapable of providing a thorough interpretation of individual values in a data distribution. But on the brighter side, it is an imperative tool that offers an understandable summary of an entire collection of data.

Most statistics assignments include several questions from this topic and students cannot afford to skip this if they are willing to score a high grade in the subject. Central tendency numerical contribute to over 35% questions in all major statistics assessment papers as well. Therefore bearing a clear concept is a must to solve them correctly.

The measure of Central Tendency

The central tendency of a data distribution can be measured using the following tools-

Mean­– Mean, generally known as average, is the most commonly used measure of the central tendency of a data set. It can be implemented for calculating the average of both continuous and discrete datasets. It can be obtained by calculating the sum of all values in a data distribution divided by the number of values in the set.

Median– Median is the value present at the center of a dataset that is arranged in ascending order. In the case of an even dataset, the arithmetic mean of the two middle values is the median of that dataset.

Mode– Mode of a dataset represents the most frequently occurring value in that distribution. Some numerical distribution can have more than one mode whereas some might not have any.

Although these are the most commonly used measures of central tendency, there are a few other measures. They are-

Geometric mean– This is used for the calculation of GDP (or Gross Domestic Product)

Harmonic mean– This is required for the calculation of speed

Geometric median– This is necessary for calculating growth rates and returns in financial calculations.

Central tendency contributes to diverse numerical. Almost all statistical calculation involves the use of at least one of the measures of central tendency. Therefore, students must consider being extremely scrupulous while preparing for this topic.

It is recommended that students devote enough time in solving examples and model questions while preparing for assessments. They can also refer to informative resources available for better learning of the topic.

Topics associated with the Advanced Statistical Studies

Nowadays, statistical studies are also conducted using sophisticated software to improve the ease of use. This simplifies the analysis of datasets that have huge volumes of information and numerous repetitive data. The use of software programs also requires an in-depth knowledge of how each of these tools performs to achieve validated data.

Some of the tools that can be used through software are mentioned as follows-

• Probability theory and distributions
• Interval estimation
• Frequency distributions
• Analysis of Random variables
• Bivariate linear regression
• Bivariate correlation
• Bivariate probability distribution studies
• Discrete parametric probability distribution
• Sampling and distribution of variables
• Point estimation and its properties
• The chi-square
• Contingency chi-square
• Contingency tables
• T-test
• Z-test
• Snedecor’s F distributions
• Continuous parametric probability distribution
• Test of parametric hypothesis
• Nonparametric techniques in statistics
• Goodness of fit
• Test of homogeneity

These software programs efficiently alleviate the issues of calculation complexity associated with statistical analysis of datasets in bulk. But it is of utmost importance that the principles of these tools are duly known by the analysts.

Statistical analysts might also be required to conduct certain calculations manually in case of any discrepancies in the system or software malfunction. Thus building strong concepts on these tools from the early academic years comes handy in the professional career as well.

Smart ways to tackle complex statistics problems

Irrespective of their professional background, people might require statistical analysis for their work. Although they can rely on external sources to get their job done, doing it themselves is always a better option. Students can save time and money by working on their statistics knowledge right from school to have an added advantage over their colleagues later in life.

Introduction to advanced statistics topics and software has admittedly vast areas that they include within their circumference. Different topics like inferential and descriptive statistics might be quite difficult to grasp primarily and that ends up scaring students initially.
