The Internal Assessment in psychology (see John Crane. Course companion. Ch 12, p388) Handout Law et al Chapter 11 p328-339 Internal assessment
The internal assessment (IA) in IB Diploma Programme psychology is a replication of a simple experiment. For all candidates the first step is to choose an experiment to replicate. In principle, it can be any experiment, but you should choose one in which it is easy to identify the variables under investigation. The success of your own experiment is to a large extent dependent on finding an appropriate study for research. It is essential that your research is based on an experiment that has been published: you should not invent something of your own.

Learning Objectives
- Experimental design
- Define the aim of the study.
- State the research and null hypothesis of a study (HL only).
- State the independent and dependant variable in an experiment.
- State the operational definitions of variables.
- Describe potential confounding variables.
- Explain the controls needed for an experiment (for example, maturation, contamination, placebo effect).
- Explain effects of participant and researcher expectations and bias (including demand characteristics, expectancy effect, observer bias).
- Explain the use of single and double-bind techniques.
- Discuss the strengths and limitations of experimental designs (for example, independent samples, repeated measures, matched pairs, single participant).
- Sampling procedures
- Discuss sampling techniques appropriate to quantitative research (for example, random opportunity, systematic, stratified.)
- Discuss how, participants are allocated to experimental and control groups (for example, matched pairs random allocation).
- Explain the concept of representative sampling.
- Explain the concept of representative sampling.
- Evaluation of Research
- Discuss the concept of internal and external validity.
- Discuss conditions that increase a study’s reliability.
- Apply descriptive statistics to analyse data (for example, mean, mode, mode, median, standard deviation.)
- Distinguish between levels of measurement (including, nominal, ordinal, interval and ratio).
- Apply appropriate graphing techniques to represent data (for example, bar chart, histogram,, line graph).
- Apply an appropriately chosen statistical test (for example, Wilcoxon matched-pairs signed-ranked test, Mann Whitney U test, Chi squared test) in order to determine the level of significance of data (HL only)
The IA needs to be completed before the examination period at the end of the semester. Click below to access timetable.
Please access the word document. Internal IB internal assessment for all the details concerning your IA.
Purpose of internal assessment
The two most important things to bear in mind are:We will allocate groups and you will be given a list of recommended studies.(ref Ideas for Internal Assessment. IB Psychology.com) In your group choose an experiment that you feel happy with. Make sure you have cleared it with me before you proceed. you will be given a proposal form please complete and handback for my records.
You can access an example of consent forms from here.
Once you are ready to collect your data I will arrange with teachers and classes to gain access to participants to carry out your study. Make sure you are well prepared. Practise amongst yourself before you proceed.
Please take the time to read through these examples.
This one received a perfect score. Extremely well written. Please read.
