    Question

    In an experiment on the effect of food marketing on purchase intentions (Laura Sjardin, Josephine Ruijs, Nora Michon and Lianne van der Poel, 2017), 182 respondents were given a picture on Instagram of a healthy “juice” (fruit juice). The respondents were randomly divided into two groups: half were shown a photo of the juice that had 28 likes; the other half a photo of a juice that had 106,613 likes. Then the respondents had to indicate to what extent to what extent they would intend to buy the juice (“buyinginterest”: a higher score means a higher buying intention). The question was whether the showing a juice with many likes leads to a higher buying intention than a juice with few likes.

    28 likes: 106,613 likes:

     

    Below are the results of an independent t-test.

    From the results of the analysis, we can see that…


    1. TRUE: The intention to buy the juice is greater when the juice has many ‘likes’ than when the juice has few ‘likes’; the difference is not significant
    2. FALSE: Intention to buy the juice is greater when the juice has many likes than when the juice has few likes; the difference is significant
    3. FALSE: The intention to buy the juice is lower when the juice has many likes’ than when the juice has few likes; the difference is not significant
    4. FALSE: The intention to buy the juice is less when the juice has many likes’ than when the juice has few likes; the difference is significant

    1. True
    2. False
    3. False
    4. False
