Introduce the learning objective and explain that choosing the right statistical test is crucial in conducting valid and reliable research.

What do you already know about choosing the right statistical test in AQA Psychology A Level?

Overview

Understanding the different types of statistical tests and when to use them is important in AQA Psychology A Level research.

Provide an overview of the lesson and explain that the students will be introduced to the most common statistical tests used in AQA Psychology A Level research.

Descriptive Statistics

Descriptive statistics are used to describe and summarize data. They include measures of central tendency (mean, median, mode) and measures of variability (range, standard deviation, variance).

Introduce descriptive statistics and explain that they are used to describe and summarize data. Provide examples of measures of central tendency and measures of variability.

Inferential Statistics

Inferential statistics are used to make inferences about a population based on a sample. They include hypothesis testing and confidence intervals.

Introduce inferential statistics and explain that they are used to make inferences about a population based on a sample. Provide examples of hypothesis testing and confidence intervals.

Independent Samples t-test

The independent samples t-test is used to compare the means of two independent groups.

Introduce the independent samples t-test and explain that it is used to compare the means of two independent groups. Provide an example research scenario.

Paired Samples t-test

The paired samples t-test is used to compare the means of two related groups.

Introduce the paired samples t-test and explain that it is used to compare the means of two related groups. Provide an example research scenario.

Chi-Squared Test

The chi-squared test is used to determine if there is a significant difference between observed and expected frequencies in categorical data.

Introduce the chi-squared test and explain that it is used to determine if there is a significant difference between observed and expected frequencies in categorical data. Provide an example research scenario.

Correlation Coefficient

The correlation coefficient is used to measure the strength and direction of a relationship between two continuous variables.

Introduce the correlation coefficient and explain that it is used to measure the strength and direction of a relationship between two continuous variables. Provide an example research scenario.

Choosing the Right Statistical Test

Choosing the right statistical test depends on the research design, the type of data collected, and the research question.

Summarize the different statistical tests and explain that choosing the right statistical test depends on the research design, the type of data collected, and the research question.

Practice Scenario 1

Present a research scenario and ask the students to identify the most appropriate statistical test to use.

Provide a research scenario and ask the students to work in pairs or small groups to identify the most appropriate statistical test to use. Walk around the room to provide support and answer questions.

Practice Scenario 2

Present another research scenario and ask the students to identify the most appropriate statistical test to use.

Provide another research scenario and ask the students to work in pairs or small groups to identify the most appropriate statistical test to use. Walk around the room to provide support and answer questions.

Quiz

Test the students' knowledge with a quiz on the different statistical tests and when to use them.

Create a quiz with multiple choice and short answer questions to test the students' knowledge on the different statistical tests and when to use them. Review the quiz as a class to provide feedback and address any misconceptions.

Conclusion

Choosing the right statistical test is crucial in conducting valid and reliable research in AQA Psychology A Level.

Summarize the lesson and emphasize the importance of choosing the right statistical test in conducting valid and reliable research in AQA Psychology A Level.
