A pharmaceutical company is conducting a study on whether or not their new vaccine is effective in preventing chicken pox. The r
esearchers rejected the null hypothesis and stated that the vaccine was effective. However, subsequent studies found out that the vaccine did not have any effect on combating chicken pox. What type of error did the researchers make
The error of type I, frequently known as a 'false positive': its error in judgment that perhaps a null hypothesis is simply rejected. This is the mistake of accepting a possible (actual interest hypothesis) hypothesis whenever the results could be attributed to chance since the researchers deny, if valid, the null hypothesis.
