– median

– standard deviation

• apply appropriate performance measures to the statistical analysis of quantitative data set(s) obtained from conducting a relevant practical investigation, including but not limited to:

– error

– accuracy

– precision

– bias

– data cleansing

• apply appropriate performance measures to the statistical analysis of a data set(s) relevant to the Scientific Research Project
• apply appropriate statistical tests of confidence to a data set(s), including but not limited to:

– Student’s t-test

– Chi-squared test

– F-test

• apply statistical tests that can determine correlation between two variables, including but not limited to:
