An experimental design is desire to accumulate the survey data or samples of large size this is because of the fact that the large sample size is expected to give more reliable results with good precision. But it may cost more time and money for conducting a research or experiment. Hence, the outcome data will be more representative for the variables used for the comparison and analysis.
<span>When designing an experiment a benefit of larger sample sizes would be more representative data. This larger sample size would lead to perfect result. The correct option among all the options that are given in the question is the second option or option "B". I hope the answer comes to your help.</span>
Suppose two objects of different masses are moving with different velocities in the same direction on a straght-line before collision. After collision, they stick together and move with common (the same) velocity
