Question

there is a new caffeinated drink produced by company nz that is supposed to help improve the production of 13 people working on data entry. company nz wants to test whether this is true, so they asked a data entry company to test the new drink on its workers. they create three groups of 50 workers each and assigns each group the same task (in this case, they are supposed to enter data xyz for 5 hours straight). group a is given the new caffeinated drink while they work. group b is given regular coffee. group c is only given water. after 5 hours, group a entered all of the data and group b has entered 90% of the data, and group c has entered only 50% of the data. Identify the: 1. Control Group: 2. Experimental Group: 3. Independent Variable: 4. Dependent Variable: 5. What should Company NZ's conclusion be? 6. How could this experiment be improved?

Answer 1

1. Control Group: Group C (the only one given water)

2. Experimental Group: Group A (given the new caffeinated drink)

3. Independent Variable: Type of drink given (water, caffeinated drink, or regular coffee)

4. Dependent Variable: Amount of data entered in 5 hours

5. Company NZ's conclusion should be that the new caffeinated drink improved production since Group A (given the new caffeinated drink) entered all of the data, Group B (given regular coffee) entered 90% of the data, and Group C (given only water) entered only 50% of the data.

6. This experiment could be improved by increasing the sample size and adding additional variables to the experiment such as the amount of caffeine in each drink, the time it takes to complete the task, and the accuracy of the data entered.
