Question

select the three things statistical significance tells us about data.
whether or not the results are 100% accurate
whether or not the results are from chance
whether or not the results from the sample can be applied to the population
whether or not the results are biased
whether or not the results are from error

1. choose true or false.

the greater the standard deviation is, the lower the variation is.
false; the greater the standard deviation is, the higher the variation is.
true

1. choose true or false.

the greater the variation is, the greater the reliability of the results is.
false; the greater the variation is, the lesser the reliability of the results is.
true

Explanation:

• Statistical significance: It helps determine if results are likely due to chance (using p - values, for example). If a result is statistically significant, it is less likely to be a random occurrence.
• Generalization to population: Statistical significance (along with proper sampling techniques) gives an indication of whether sample results can be extended to the population. For example, in hypothesis testing for a population parameter based on a sample.
• Standard deviation and variation: Standard deviation is a measure of variation. A larger standard deviation means more spread out data, i.e., higher variation.
• Variation and reliability: Higher variation in data (more spread out) makes it less likely that results are consistent and thus reduces the reliability of the results.

Answer:

• For the first part (select three things):
• whether or not the results are from chance
• whether or not the results from the sample can be applied to the population
• For the second question (10): False; The greater the standard deviation is, the higher the variation is.
• For the third question (11): False; The greater the variation is, the lesser the reliability of the results is.
