How do you describe a positive graph?
A positive slope means that two variables are positively related—that is, when x increases, so does y, and when x decreases, y decreases also. Graphically, a positive slope means that as a line on the line graph moves from left to right, the line rises.
How do you describe a curved graph?
The relationships shown in ‘curved graphs’ are more complex to describe. One possibility is that ‘as x increases, y increases slowly at first and then more rapidly’ (Figure 7.4a) or that ‘as x increases, y increases rapidly at first and then more slowly’ (Figure 7.4b).
How do you explain a scatter plot?
A scatter plot (aka scatter chart, scatter graph) uses dots to represent values for two different numeric variables. The position of each dot on the horizontal and vertical axis indicates values for an individual data point. Scatter plots are used to observe relationships between variables.
How do you know if a correlation coefficient is statistically significant?
Compare r to the appropriate critical value in the table. If r is not between the positive and negative critical values, then the correlation coefficient is significant. If r is significant, then you may want to use the line for prediction. Suppose you computed r =0.801 using n = 10 data points.
What makes a coefficient statistically significant?
The coefficients describe the mathematical relationship between each independent variable and the dependent variable. The p-values for the coefficients indicate whether these relationships are statistically significant.
What is an example of statistical significance?
Statistical Significance Definition For example, if you run an A/B testing experiment with a significance level of 95%, this means that if you determine a winner, you can be 95% confident that the observed results are real and not an error caused by randomness.
What does it mean if something is not statistically significant?
This means that the results are considered to be „statistically non-significant‟ if the analysis shows that differences as large as (or larger than) the observed difference would be expected to occur by chance more than one out of twenty times (p > 0.05).
What does statistically mean?

How do you use statistically in a sentence?
Statistically your odds are better to strike a ship. Statistically speaking, women cheat on their spouses less than men do. Statistically , few children who are identified as needing treatment for mental health conditions actually receive the care that they need. However, the results were statistically shocking.
What does Statistically speaking mean?
“Statistically speaking” is a somewhat clichéd phrase that tends to divert the responsibility for opinions onto the statistical data that supposedly underlays them. It means that you have either performed a statistical analysis or you are reporting on the results of a s tatistical analysis.
Why descriptive analysis is important?
Descriptive statistics are very important because if we simply presented our raw data it would be hard to visualize what the data was showing, especially if there was a lot of it. Descriptive statistics therefore enables us to present the data in a more meaningful way, which allows simpler interpretation of the data.
What is the goal of descriptive statistics Brainly?
Answer: The main purpose of descriptive statistics is to provide a brief summary of the samples and the measures done on a particular study. Coupled with a number of graphics analysis, descriptive statistics form a major component of almost all quantitative data analysis.
What are the advantages of descriptive research design?
Advantages of Descriptive Studies Descriptive (including ecological) studies are generally relatively quick, easy and cheap to conduct. Exposure data often only available at the area level. Differences in exposure between areas may be bigger than at the individual level, and so are more easily examined.
