DIFFERENCE BETWEEN DESCRIPTIVE AND INFERENTIAL STATISTICS

First and foremost, it is vital for you to understand the meaning of statistics. It is a field of science that is concerned with the developing and studying methods for collecting, analyzing, interpreting, and presenting empirical data. Statistics is the cornerstone of other areas and provides the basis of inferential and descriptive statistics.

Due to the diversity of the subject, it is classified into two broad types, Descriptive and inferential statistics. In this article, you will learn about the two models and their differences. Also, if you need clarity on the topic or you're asking yourself, "Who can I rely on to do my statistics homework?" Worry no more, we got you covered. Contact us today for assistance. Without further ado let us proceed to the differences between descriptive and inferential statistics.

Descriptive Statistics

This is a summary statistic that quantitatively describes and summarizes features in a collection of info. It is solely concerned with the properties of the observed data and does not rest on the assumption that the data comes from a large population. It provides simple summaries about the sample and the observations that have been made. It allows you to characterize data based on several assumptions as follows.

It's a measure of dispersion as it identifies the spread across by stating the intervals. A measure of frequency by showing how often a scenario or something occurs. Measure of central tendency; this locates the distance of various parts. It is a measure of position; this helps in describing how scores fall in place with one another.

Inferential Statistics

Statistical inference is the process of using data analysis to deduce properties of an underlying probability distribution. It makes a proposition about a community using data drawn from the population with some form of sampling. There are three types of inferential statistics.

ANOVA

Well known as Analysis of variance is used to compare means. Unlike the T-test, it compares multiple means at the same time. Types of ANOVA are one-way ANOVAs, repeated measures ANOVAs and factorial ANOVAs.

T-Tests

It can also be used to compare means. It compares only one sample at a time. The different types of t-tests include one sample t-test, independent sample t-test, and dependent samples.

Regression

Regression is a procedure that allows you to predict an outcome variable based on knowledge of some predictor variable.

The Differences between differential and inferential statistics

Differential and inferential statistics seem to be similar due to their shared heritage and knowledge. However, several factors separate the two subfields. Below are some of their differences.

Descriptive statistics gives information that describes the data in some manner, whereas inferential statistics is used to collect data from a large population. Descriptive statistics tend to describe the data while on the other side, inferential statistics conclude the data.

In descriptive statistics, analysis of data helps to describe, show or summarize data in a meaningful way such that patterns might emerge from the info. On the other hand, inferential statistics uses statistical information to learn and study about the population.

Graphical representations, like histograms, bar graphs, and pie charts, are used in differential statistics whereas inferential statistics makes use of probability distributions, hypothesis testing, correlation testing, and regression analysis.
