What does it mean for the finding of a statistical analysis of data to be statistically significant?
Data is statistically significant if the p (probability) value is below a certain level (ex: 5% or 1%). The p value describes how often one would receive the results they got if left to chance alone. The lower the p value, the less likely it is that your results were due to chance and is stronger evidence against the null hypothesis. Also important to keep in mind is that just because something is statistically significant does not mean it is practically significant.
What is data collected method?
Data Collection is an important aspect of any type of research study. Inaccurate data collection can impact the results of a study and ultimately lead to invalid results.
How do you round 0.004560 to 2 significant figures?
0.004560 to two significant figures results in: 0.0046
When data points in a set of a data are extreme enough to have a significant effect on the mean what are they called?
Such a data point is called an outlier.
What problems occur when collecting weather data manually?
You might receive anonymous results (incorrect data). By using Automated weather equipment, the results will be more accurate.
Why was this hyphothesis rejected?
The hypothesis was rejected because the results did not support it based on the data collected during the experiment. The data may have shown no significant difference or opposite results than what was predicted in the hypothesis, leading to its rejection.
What do outliers indicate?
In statistics, outliers are values outside the norm relative to the rest of collected data. Many times they can skew the results and distort the interpretation of data. They may or may not indicate anything significant; they might just be an anomalous data point that is not significant. It is difficult to tell.
Why should academic journals have such stringent standards?
Statistics can easily be used to misrepresent data enough to show statistically significant results.
What do you call the results of an experiment?
Observations and measurements made during an experiment are called the data.

What is the significance of a hard cutoff in the context of data analysis and how does it impact the accuracy of the results?
A hard cutoff in data analysis refers to a strict boundary or threshold used to categorize or filter data. It is significant because it can affect the inclusion or exclusion of data points, which in turn can impact the accuracy of the results. If the cutoff is set too high or too low, important data may be missed or irrelevant data may be included, leading to biased or inaccurate conclusions.
What is a researcher who engages in p-hacking trying to achieve?
A researcher who engages in p-hacking is trying to manipulate or cherry-pick data in order to find statistically significant results, even if the results are not truly meaningful or valid.
How does in the data affect Experimental results?
Bias in the data is inaccurate data. Any error in data will yield false results for the experiment. Experiments by their nature must be exact. Many trials are not accepted until the results can be duplicated.
Are data and results the same thing?
Oh, what a lovely question! Data and results are like different colors on our palette. Data is the raw material, like the colors on our palette, and results are what we create with that data, like a beautiful painting. Just like how we mix and blend colors to create a masterpiece, we analyze and interpret data to derive meaningful results.
What is the BEST way to state the relationship between data and results?
"Data" are the facts you collect from your experiment, while "results" are your interpretation of what the data mean.
Outlines the steps in an Analytical Procedures?
Define the objective and scope of the analytical procedures. Collect relevant data and information. Develop expectations based on historical data or industry norms. Compare actual results to expected results. Investigate significant variances or anomalies. Document findings and conclusions. Communicate results to appropriate parties.
