Inferential statistics enable you to draw inferences and make predictions based on your data, whereas descriptive statistics summarize the properties of a data collection. It is an area of mathematics that enables us to identify trends and patterns in a large number of numerical data....

Sampling error occurs when a sample drawn from a population deviates somewhat from that true population. Large sampling errors can lead to incorrect estimates or inferences made about the population based on statistical analysis of that sample. In general, sampling errors can be placed into four cat...
Critical thinkers may eventually come to a point when they have to apply what they know either in thought or deed. This type of critical thinking skill is called prediction -- the method of applying your inferences to essentially guess what will happen. Different professional fields apply critical...
Inferential statistics Both types of statistics have their parameters, which are measurements of a statistical population (a set of events, objects, cases, or items that are similar in some aspect or belong to the same universe) that describe the attribute of that population. Descriptive statist...
The number of males in the data set is 2. The number of females in the data set is 3. The number of individuals identifying as other is 1. The number of non-males is 4. Univariate vs. Bivariate In descriptive statistics, univariate data analyzes only one variable. It is used to ident...
and you want to understand the purchasing behavior of your customers. Instead of surveying every single customer, which may be impractical, you survey a representative sample of customers. Inferential statistics would then help you make inferences about the preferences and behavior of your entire custo...
2. Analyzing Data in Quantitative Research Quantitative research involves working with numerical data, making it suitable for statistical analysis. This method is often used to quantify relationships, measure variables, and draw statistical inferences. Follow these steps to analyze quantitative data effectiv...
What are the Fundamentals of Hypothesis Testing? Hypothesis testing is a technique for interpreting and drawing inferences about a population based on sample data. It aids in determining which sample data best support mutually exclusive population claims. Null Hypothesis (H0) - The Null Hypothesis is...
