Exploring Experimental Design
Today, you will dive into the role of a researcher examining the effect of a new smartphone application that is claimed to enhance productivity in individuals aged [latex]18 - 25[/latex] years.

The researcher randomly sampled [latex]200[/latex] individuals from the age group and divided them into two groups. Group 1 was asked to use the productivity app daily, while Group 2 used an app that was designed to have zero impact on their productivity levels. Consider Group 2 the control group. The researcher was aware of which app each group was using but did not share this information with the participants. After a month, it was found that individuals in Group 1 were reportedly more productive than those in Group 2.
