Informal experimental designs are _________Choose one optionBefore-and-after without control designAfter-only with control designBefore-and-after with control designAll the above

In ________ design a single test group or area is selected and the dependent variable is measured before the introduction of the treatment. The treatment is then introduced and the dependent variable is measured again after the treatment has been introduced. The effect of the treatment would be equal to the level of the phenomenon after the treatment minus the level of the phenomenon before the treatmentChoose one optionBefore-and-after with control designBefore-and-after without control designAfter-only with control designNone

In _______ design two groups or areas (test area and control area) are selected and the treatment is introduced into the test area only. The dependent variable is then measured in both the areas at the same time. Treatment impact is assessed by subtracting the value of the dependent variable in the control area from its value in the test areaChoose one optionBefore-and-after without control designBefore-and-after with control designAfter-only with control designNone
