What would you use to represent correlation visually? Scatter plot Polygon Histogram Bar graph
If you have a scatter plot graph and it reads moderate positive correlation is r=0.5 When you look at the r value how is that represented on the scatter plot?
How would you describe, verbally, a correlation of .33, in terms of how the scatter plot should look? BE SPECIFIC. Refer to the direction of the slope, generally, and whether the scatter will be widely spread out or tightly clustered around a line.
A frequency polygon would be an example of what kind of data presentation? tabular presentation b. graphic presentation numerical presentation d. historical presentation Which of the following types of graphs could be used with data at the ordinal level? Bar graph b. Histogram frequency polygon d. stacked line Which of the following types of graphs could be thought of primarily as a "curve"? Bar graph b. Histogram Frequency polygon d. Pie...
14) Explain why the following bar graph is misleading and how you would fix it. (Hint: Section. 2.3 #25) 3.00 52.50 $2 00 $1 50 51 08 MILK 51 00 0 10 Fal 2011 11) Histograms are very important to identify the 'shape' of a quantitative dataset. 4 A) Which histogram would be described as fairly bell-shaped? B) Which histogram would be described as fairly uniform? C) Which histogram would be described as skewed to the right or skewed positively?...
frequency polygon? . Why should there be no space between the bars of a histogram, but space between the bars of a bar graph? What is wrong with plotting a cumulative fre quency distribution for a variable that has a nominal scale?
5. What would the scatter plot show for data that produce a Pearson correlation of r = +0.88? (1 pt) a. Points clustered close to a line that slopes up to the right b. Points clustered close to a line that slopes down to the right c. Points widely scattered around a line that slopes up to the right d. Points widely scattered around a line that slopes down to the right
which of the following numbers represents the correlation for
the following scatter plot?
im not sure if it would be -.67 or -.28??

Discuss an alternative scenario to represent the data in
the scatter plots. In this scenario, assume there is correlation
but where it would be inappropriate to conclude
causation.
In the first scatter plot, the points represent numbers of
customers conducting business during the timeline of the
quarantine. X- axis being number of weeks projected for duration of
quarantine and Y- axis representing customers that are requesting
services. The first scatter plot shows that there is a positive
linear correlation between...

2. Use a graphing calculator or a spreadsheet to a create scatter plot, line of best fit, and determine the correlation coefficient for the following data that relates a person's age and his/her height. Classify the type of correlation that is shown AGE 20 40 65 80 92 108 a from each of the following. Label the axes to indicate the independent and dependent variable 3. Sketch a scatter plot that could represent dat a. peopie's ages (starting...
You are given the following regression equation for a scatter plot which The displays data Weight of Car (in pounds) and y = Miles per Gallon in City: for x = y = -0.006.0 + 42.825 p2 = 0.7496 (Note: The scatter plot graph is attached to the Canvas assignment as a separate document.) (a) Find the value of r based on the information given. (b) Based on your value of r, what conclusion can you make about the correlation...
