For the next set of scores fill in the appropriate cells. The mean is

A score between 70-80 is likely to fall within this range. It means that 30 % of scores within a population will fall in this range. Probabilities can be estimated by examining the distribution of scores within a given population.

This means that in most cases, only 20% will exceed the threshold. The calculation can be done using other statistical methods, such as finding an area under the curve of a normal distribution or computing cumulative probabilities based on frequency tables. In either case, it’s important to note that these estimates may not always reflect real world results due to potential sampling errors or other factors outside our control.

In general, knowing how to calculate and understand probabilities helps quantitative researchers draw better conclusions about their data. By having knowledge about what kinds of outcomes are possible—and more importantly, how likely they are—we can make better informed decisions based on our findings when attempting to answer questions related to various topics in our studies.
