If the sample mean is noticeably different from the original population mean, then we have evidence that the treatment had an effect.. – Students should be able to state the hypotheses and locate the critical region.
The next step is to determine what kind of sample data would be reasonable if this hypothesis is true, and what kind of sample data would be very unlikely. The term “very unlikely” is defined by the alpha level for the test

Understanding Null Hypothesis Testing – Research Methods in Psychology – 2nd Canadian Edition [6]

– Explain the purpose of null hypothesis testing, including the role of sampling error.. – Describe the basic logic of null hypothesis testing.
As we have seen, psychological research typically involves measuring one or more variables for a sample and computing descriptive statistics for that sample. In general, however, the researcher’s goal is not to draw conclusions about that sample but to draw conclusions about the population that the sample was selected from
These corresponding values in the population are called . Imagine, for example, that a researcher measures the number of depressive symptoms exhibited by each of 50 clinically depressed adults and computes the mean number of symptoms

How Hypothesis Tests Work: Significance Levels (Alpha) and P values [7]

Hypothesis testing is a vital process in inferential statistics where the goal is to use sample data to draw conclusions about an entire population. In the testing process, you use significance levels and p-values to determine whether the test results are statistically significant.
But, what do significance levels, P values, and statistical significance actually represent? Why do we even need to use hypothesis tests in statistics?. I use graphs and concepts to explain how hypothesis tests function in order to provide a more intuitive explanation
To start, I’ll demonstrate why we need to use hypothesis tests using an example.. A researcher is studying fuel expenditures for families and wants to determine if the monthly cost has changed since last year when the average was $260 per month

Hypothesis testing, type I and type II errors [8]

Hypothesis testing is an important activity of empirical research and evidence-based medicine. A well worked up hypothesis is half the answer to the research question
The present paper discusses the methods of working up a good hypothesis and statistical concepts of hypothesis testing.. Karl Popper is probably the most influential philosopher of science in the 20thcentury (Wulff et al., 1986)
The popularity of Popper’s philosophy is due partly to the fact that it has been well explained in simple terms by, among others, the Nobel Prize winner Peter Medawar (Medawar, 1969). Popper makes the very important point that empirical scientists (those who stress on observations only as the starting point of research) put the cart in front of the horse when they claim that science proceeds from observation to theory, since there is no such thing as a pure observation which does not depend on theory

What is Hypothesis Testing in Statistics? Types and Examples [9]

In today’s data-driven world, decisions are based on data all the time. Hypothesis plays a crucial role in that process, whether it may be making business decisions, in the health sector, academia, or in quality improvement
In this tutorial, you will look at Hypothesis Testing in Statistics.. Hypothesis Testing is a type of statistical analysis in which you put your assumptions about a population parameter to the test
Let’s discuss few examples of statistical hypothesis from real-life -. – A teacher assumes that 60% of his college’s students come from lower-middle-class families.

Hypothesis Testing | A Step-by-Step Guide with Easy Examples [10]

Hypothesis Testing | A Step-by-Step Guide with Easy Examples. Hypothesis testing is a formal procedure for investigating our ideas about the world using statistics
– State your research hypothesis as a null hypothesis and alternate hypothesis (Ho) and (Ha or H1).. – Collect data in a way designed to test the hypothesis.
– Present the findings in your results and discussion section.. Though the specific details might vary, the procedure you will use when testing a hypothesis will always follow some version of these steps.

Chapter 12: Repeated Measures t-test – Introduction to Statistics for Psychology [11]

So far, we have dealt with data measured on a single variable at a single point in time, allowing us to gain an understanding of the logic and process behind statistics and hypothesis testing. Now, we will look at a slightly different type of data that has new information we couldn’t get at before: change
This is a very powerful thing to do, and, as we will see shortly, it involves only a very slight addition to our existing process and does not change the mechanics of hypothesis testing or formulas at all!. Researchers are often interested in change over time
In each of these cases, we measure a single variable at different times, and what we are looking for is whether or not we get the same score at time 2 as we did at time 1. This is a repeated sample research design, where a single group of individuals is obtained and each individual is measured in two treatment conditions that are then compared
