What is regression analysis and inferential analysis?
Regression AnalysisIt is a collection of statistical techniques to understand the relationship among several independent variables and one or more dependent random variables.Inferential AnalysisIt is collection of mathematical techniques to make prediction about unseen large data sets on the basis of a study of available small samples of that data.Regression analysis is a specific way of performing inferential analysis.
Does inferential statistics involve using a suitable population to draw a conclusion from a sample drawn from that population?
It is strangely worded like that, but the answer is yes.
Differences between descriptive and inferential statistics?
All statistical tests are part of Inferential analysis; there are no tests conducted in Descriptive analysis · Descriptive analysis- describes the sample's characteristics using… o Metric- ex. sample mean, standard deviation or variance o Non-metric variables- ex. median, mode, frequencies & elaborate on zero-order relationships o Use Excel to help determine these sample characteristics · Inferential Analysis- draws conclusions about population o Types of errors o Issues related to null and alternate hypotheses o Steps in the Hypothesis Testing Procedure o Specific statistical tests

Deffirence of discriptive statistics to inferential statistics?
Descriptive statistics is the term given to the analysis of data that helps describe, show, or summarize data in a meaningful way such that patterns might emerge from the data. Inferential statistics are techniques that allow us to use population samples to make generalizations about the populations from which the samples were drawn.
What are two main types of analysis?
There are six types of analysis, including descriptive and exploratory. Inferential, predictive, causal, and mechanistic are the other types of analysis.

What are the division of statistics?
The division of statistics are generally divided into two groups: inferential and descriptive. Inferential statistics require that a conclusion is drawn from data, based almost solely on human inference. Descriptive statistics are numbers that describe a set of data.
What is inferential data?
There is no inferential data. There is inferential statistics which from samples, you infer or draw a conclusion about the population. Hypothesis testing is an example of inferential statistics.
