# NURS 6051 Week 9: Introduction to Statistics

Welcome to week 9, we are going to look at what you might expect to cover in NURS 6052 week 9 Introduction to Statistics course. Statistics is defined as the study of collecting, analyzing, and interpreting data.

In week 9, you will cover hypothesis testing. This requires you to make statements on population parameters and test them using sample data.
You will also look into type 1 and type II errors. Type 1 errors always occur in statistics, mostly, when we reject a true null hypothesis, on the other hand, type 2 errors occur whenever we fail to reject a false null hypothesis.

Another aspect you will come across is confidence intervals. These are a range of values that statisticians are optimistic about as they contained true population parameters.

T-tests come in as yet another parameter in statistics, they are used to establish significant differences between means of two groups.
ANOVA (Analysis of variance) is yet another statistical test that you will use to determine the significance of the difference between two or more means.

Chi-Square tests will also be introduced in week 9, they are used to determine any significant associations between two variables.
Week 9 will also get you through how to perform statistical tests using existing software like Excel or SPSS. You will also learn how to interpret the results from these tests. You will also dwell on why it is important to learn statistics while taking nursing courses and how you can use statistical data to make informed decisions.
