Join Barton Poulson for an in-depth discussion in this video Single proportion: Hypothesis test and confidence interval, part of SPSS Statistics Essential Training.
- For many people, when they think of statistics,…they think of inferential statistics, and not always fondly.…Of course, there's a lot more to statistics and data…analysis than the calculation of probability values,…as should be evident by the amount of time…we've spent so far on graphics and descriptive statistics,…but the ability to go beyond the data at hand…and make inferences about a larger group of people,…hence the name, inferential statistics,…is one of the great beauties of analysis.…In this group of movies, I want to start…with the simplest kinds of inferential statistics,…tests for one variable at a time.…
There are a few different procedures that we'll cover…such as confidence intervals and hypothesis tests…for scale variables and proportions as well as…the distribution of a single categorical variable.…But let's start with what is probably the simplest and most…familiar given its ubiquitous presence in political polls,…the confidence interval for a single proportion.…To do this, I'm going to come up to Analyze,…
