Dove was interested in the effects of chocolate on well-being. She randomly assigned 20 participants to two groups. Both groups ate as they normally would, but one group was instructed to each eat a 1-ounce square of dark chocolate after both lunch and dinner. After the participants spent four weeks on this diet, Dr. Dove asked each one to complete a questionnaire measuring well-being (happiness, contentment). However, Dr. Dove was surprised to find that the chocolate had no effect: Both groups, on average, scored the same on the well-being measure. Help Dr. Dove troubleshoot her study (Hint: this is an example of a null effect).

She needs to change the manipulation of her study by changing the measurements, possibly.

Explanation:

The Null Effect is a result, in science experiments that do not produce the desired or proposed result. Such experiments do not help to support the hypothesis. The word 'null' means 'nothing' or 'empty' thus the results in an experiment that does not give the desired results as proposed are term as 'null results or effects.'

In the given case, the null effect of Dove's experiment is because of the improper measurement of the variable. She can troubleshoot her experiment by changing the measurements of her variable, which is chocolate. It is because an ounce of chocolate equals to no chocolate. So when the subjects took an ounce of chocolate is did not produce the desired result as the measurement was not correct. She can change the measurements of the chocolate to see the desired result.
