Step 1: Carefully follow the teacher's IA task instructions during lessons. You can find the teacher's materials below.

Step 2: Carefully internalize the Psychology IA assessment criteria and ethical guidelines. Forthermore, carefully study pages 487–512 from your textbook.

Step 3: Form groups for your replication phase. Maximum size for a group is four people. 

Step 4: As a group, choose an original study for replication. Teacher has provided suitable options below. You can choose a study outside the teacher's options, but you need to find the original study and approve your choice with the teacher. If more than one group chooses the same study for replication, pooling data is encouraged. This means that your procedures should be similar. Cooperate.

Step 5: Carefully read the original study.

Step 6: Plan your replication based on the original study:

- Make sure that you have only ONE independent variable (IV) with only TWO conditions in your procedure!
- Decide the level of measurement (nominal, ordinal, interval or ratio data)
- Decide the experimental design: independent measures or repeated measures? Do NOT use repeated measures with nominal data!
- Decide the type of your research hypothesis: one-tailed or two-tailed?
- Make sure that your procedure follows the ethical guidelines!
- Carefully compile a consent form that fits your procedure and follows the ethical guidelines! Use the example files below.
- Carefully compile an experimental procedure that includes clear instructions for the participants. In addition, create a clear way to gather data with effective data collecting forms. 
- Approve your procedure and consent form with the teacher.

Step 7: Arrange a time and place for your replication with the help of the teacher. Make sure that you have enough participants for your replication. Around 30 participants is enough. Do the replication according to your plan and collect your data.

Step 8: Start working with your IA report independently. You do your replication and collection of data in groups, but every IA report is personal. 

- Take a look at the 22/22 exemplar study. This work gives you guidelines on how to write the IA report. The 22/22 work with examiners comments can be extremely useful. 
- Download the IA base document below and rename it. Do NOT use the online version of the word. Use the full desktop version. Do NOT change the settings of the Word-document. Use the styles to fully implement the APA style. The IB Psychology IA report should be written with APA style. Ask the teacher for help if you encounter any difficulties in APA referencing system. The Psychology EE page contains lots of links and instruction related to the APA system.
- Carefully follow the assessment criteria with each part of the IA report. Make sure that you have all the elements in your IA report.
- Remember to draw appropriate graphs and/or tables that address your hypothesis with explanations for descriptive statistics.
- Use Social Science Statistics (or similar) for inferential statistics. Use .05 significance level. Remember to choose right test to suit your hypothesis (one-tailed or two-tailed). Options with information are below:
* Unrelated t-test calculator (parametric test for interval/ratio data with independent measures designs).
* Related t-test calculator (parametric test for interval/ratio data with repeated measures design).
* Mann-Whitney U test calculator (non-parametric test for ordinald/interval/ratio data with independent measures design).
* Wilcoxon Signed-Rank test calculator (non-parametric test for ordinal/interval/ratio data with repeated measures design).
* Chi-square test calculator (non-parametric test for nominal data with independent measures design).
- Each test gives you a test statistics, a number. You need to compare this test statistics to critical values table found below. You should use the .05 column in the tables with right degrees of freedom (df). Degrees of freedom can be found from your calculations or from your texbook pages 502–509.
* t-tests: if your test statistics is higher than the crital value, your result is statistically significant.
* Mann-Whitney U test and Wilcoxon signed-rank test: if your test statistics is smaller than or equal to the critical value, your test result is statistically significant.
* Chi-square test: if your test statistics is higher than or equal to the crital value, your results is statistically significant.
- Carefully read texbook pages 502–509. Those pages give you instructions on how to report the results of your inferential statistics in your IA report.
- Remember to interpret the calculations from your inferential statistics test and link them to your hypothesis. Include a screen capture of the calculations in your appendices.
- Remember to include all relevant data to your Appendices (raw-data tables, calculations of inferential statistics, unfilled consent form, copy of standardized procedures and possible debrefing notes). 

Step 9: Count the words of your Introduction, Exploration, Analysis and Evaluation with the help of the IBO's EE word count system. Title page, Table of contents, References and Appendices are NOT included in the word count. Make sure that you stay within the 1800 to 2200 word limit.

Step 10: Upload the first submission of your IA report to ManageBac by the deadline provided by the teacher. The teacher will comment your first submission as soon as possible. Remember that this is the only time you get extensive feedback on your IA report. Try to be as complete as possible.

Step 11: Finish your IA report with the help of the teacher's feedback and upload the final submission of your IA report to ManageBac by the deadline provided by the teacher. In general, all IA tasks in IB Psychology should be finished by the end of the fourth term during IB1 year. 

Step 12: After receiving your candidate codes in IB2 year, update your candidate codes to your IA report and re-upload your completely finished work to ManageBac. This is the only time you are allowed to modify your IA report after step 11 in IB1 year. 

Step 13: Relax and enjoy life!
