Editing Student's t-test (section)

===A design which includes both paired observations and independent observations===
When both paired observations and independent observations are present in the two sample design, assuming  data are missing completely at random (MCAR), the paired observations or independent observations may be discarded in order to proceed with the standard tests above. Alternatively making use of all of the available data, assuming normality and MCAR, the generalized partially overlapping samples ''t''-test could be used.<ref name="Partover">{{cite journal|last1=Derrick|first1=B|last2=Toher|first2=D|last3=White|first3=P|title=How to compare the means of two samples that include paired observations and independent observations: A companion to Derrick, Russ, Toher and White (2017)|journal=The Quantitative Methods for Psychology|date=2017|volume=13|issue=2|pages=120–126|doi=10.20982/tqmp.13.2.p120|url=http://eprints.uwe.ac.uk/31765/1/How%20to%20compare%20means......%20BD_DT_PW.pdf|doi-access=free}}</ref>
