To test the effectiveness of using a dab of honey to prevent infection in a cut, parents of children in a childcare facility were instructed to wash the wounds of their children with soap and water and then place a dab of honey on the cut. each cut was then monitored for infection. at the end of the study, the percentage of the twenty eight children who had cuts that became infected was computed. does this study have randomization?

This is this not a valid experiment because there is no randomization. T here is no blinding as parents may use more care and those monitoring for infection may be less stringent in their diagnosis.  There is no control group that gets a placebo for comparison.  Parents may be more careful of the cuts of their children since they know they are in an experiment. And t he results may not apply to all children since only those children in a day care facility participated.

it is loom ps i took the test
