Final answer:
The statement is false; statistical training can significantly improve decision-making quality by providing individuals with the necessary tools and knowledge to analyze and interpret data effectively and make more informed decisions.
Step-by-step explanation:
The statement that quality of decision making cannot be improved even with statistical training is false. Statistical training equips individuals with the tools and methodologies to gather, analyze, interpret, and present data in a meaningful way. Through statistical training, individuals can improve their ability to make decisions based on empirical evidence, increase their awareness of potential biases or fallacies, and ultimately make more informed and reliable decisions.
For example, understanding the importance of larger sample sizes can help in making more reliable generalizations from experiments. Additionally, being aware of confounding variables, as mentioned in the scenario where an improvement cannot be attributed specifically to software or exercise, is crucial in drawing accurate conclusions from data.
Furthermore, when it comes to democratic decision making, recognizing the limitations of systems like the majority rule can inform the creation of fairer and more effective methods of collective decision making, especially in situations where there are more than two choices.
