Question

When 6 Mentos candies are added to a 2-liter carbonated soda, the carbonation is released quick enough to allow a rocket attached to the bottle to fly up in the air. Ralph wants to know if the type of soda used affects the height of the rocket. So he ran 100 trials for each of the following types of soda: diet coke, regular coke, sprite, root bear, and sam’s cola. Ralph hypothesized that root bear would have the highest rocket launch because it has higher carbonation than the other sodas. What statistical test should he use to analyze his data? independent-measures t-test repeated-measures t-test (paired-samples t-test) independent-measures ANOVA repeated-measures ANOVA

Explanation / Answer

Answer: The statistica test should be used to analyzed tha data is Independent-measures ANOVA.

Here we use One way ANOVA becuase we have more than 2 treatment groups for analysis , i.e. the different types of Soda : diet coke, regular coke, sprite, root bear, and sam’s cola

And Also We use Independent Measure ANOVa, because the means of different groups are independent to each other.
