In this course we will discuss Foundations for Inference. Descriptive statistics describe the characteristics of your numerical dataset, while inferential statistics are used to make inferences from subsets of data so you can better understand the larger datasets from which the subset is taken. For more on inferential statistics, check out this overview from Purdue University. With descriptive statistics you are simply describing what is or what the data shows. Confidence Intervals--Confidence intervals using z are performed with the CONFIDENCE FUNCTION within the function wizard. Welcome to Inferential Statistics! Statistical analysis allows you to use math to reach conclusions about various situations. Inferential statistics allows us to draw conclusions from data that might not be immediately obvious. With inferential statistics, you are trying to reach conclusions that extend beyond the immediate data alone. About this Course. So in this tutorial we are going to go through some of the concepts of statistsics to learn and understand inferential statistics and master it. Hypothesis testing is a tool used in inferential statistics to determine the effectiveness of an experimental treatment. View more presentations from psychexchange.co.uk.

We trust a random sample to represent different segments of society in close to the appropriate proportions (provided the sample is large enough; see below). There are many differences between descriptive and inferential statistics. In addition to videos that introduce new concepts, you will also see a few videos that walk you through application examples related to the week's topics. Descriptive and Inferential Statistics. Inferential Statistics with Excel--Remember that t-scores are most often used since population parameters required for use of z-scores are seldom known. Inferential statistics is extremely useful in data analytics, and any capable data scientist must have an idea of what it is in order to understand and solve many real-world problems fully.
