What is a statistically significant result?
A result is statistically significant if:it is unlikely to have occurred by chance
What type of research describes the strenghth and direction of relationships between two variables?
Correlation analysis. But you will need a lot more knowledge of statistics before you can decide whether the result is [statistically] significant or not, and if it is, what that means.
What is meant by F distribution equals 1.0251?
The F distribution is a function defined over non-negative real numbers, and it takes all sorts of values over that domain. In isolation, none of the values mean anything. An F-test, is a test based on the ratio of two variances from [approximately] normal distributions and a full interpretation requires information about the degrees of freedom. The degrees of freedom determine how much greater than 1 the value of the F-statistics can be before the result is statistically significant. However, a value near 1, such as this will not be statistically significant.
How many significant figures would be in theresult of the multiplication of 2.305956 and 198.40?
The result is 457,50 - with two significant figures.
How does conversion factors affect the number of significant figures in a problem?
If the conversion factor is exact, then the number of significant figures in the answer is the same as the number of significant figures in the original number.If the conversion factor is an approximation, then the number of significant figures in the result is the lesser of this number and the number of significant figures in the original number.

How can a result be described as statistically significant but not practically significant?
You buy a thousand lottery tickets (different numbers) and win nothing. That is statistically significant because the chances of that happening purely by chance are pretty slim. But if the lottery is operated properly, the result is not practically significant. There is nothing that can be done. Tough!
What is meant by the term Statistically Significant Difference If it is statistically significant does that automatically mean it is managerially significant?
You make assumptions about the nature of the distribution for a set of observations and determine a pair of competing hypotheses - a null hypotheis and an alternative. Based on the null hypothesis you devise a test for a statistic that is based on the observations. Assuming the null hypothesis is true, if the probability of observing a test statistic that is at least as extreme as the one obtained is smaller than some pre-determined level (that is, if the observations are very unlikely under the null hypothesis) then the result is said to be statistically significant. This does not automatically imply managerial significance since, among other factors, the latter must take account of the consequences (costs) of making the wrong decision.

What circumstances can a small treatment effect be statistically significant?
For a given experiment, and a given sample size, there is a probability that a treatment effect of a given size will yield a statistically significant finding. That is, if the treatment effect is 1 unit, then that probability (the power) might be 50%, and the power for a treatment effect of 2 units might be 75%, etc. Unfortunately, before the experiment, we don't know the treatment effect size, and indeed after the experiment we can only estimate it. So a statistically significant result means that, whatever the treatment effect size happens to be, Mother Nature gave you a "thumbs up" sign. That is more likely to happen with a large effect than with a small one.
How is the scientific process used to solve problems?
create hypthesis, determine testing method to evaluate and threshold needed to surpass to consider result valid in the sense of the hypothesis, test statistically significant, compare result to threshold defined, if under: drop hypothesis, if equal or above: accept as correct

As a result of the rule that you use the definition of the term - such as significant digits - when finding them for a number.
The most significant result of the Louisiana Purchase in America was the?
The westward expansion was the most significant result of the Louisiana Purchase in America. The purchase was made in 1803.
When multiplying and dividing measured quantities the number of significant figures in the result should be equal to the number of significant figures in what?
The number of significant figures should be equal to the significant figures in the least precise measurement.

The result is 457,50 - with two significant figures.
Which was a significant result of the Depression of 1929?
