How do you know when there is positive correlation on a graph?
when the points on the graph are close to each other;)
What type of graph best shows how something changes over a period of time?
A line graph shows change over a period of time.
Which type of graph best shows the distribution of the weights of a certain type of animal at a zoo?
bar graph
Information collected by counting can best be displayed on a?
A bar graph is information that is collected by counting can be displayed on this graph. A pie graph is a graph that shows information as parts of a circle
How do you discuss trends that occur by looking at a graph?
When both axis' are increasing it is a positive correlation. When both are decreasing it is a negative correlation. When the dots are all over the place then there is no correlation.
What is the correlation on a graph?
a correlation on a graph is when the line of best fit is positive, negative or none.
What shows a correlation which may be positive or negative between two sets of data?
I believe you are asking how to identify a positive or negative correlation between two variables, for which you have data. I'll call these variables x and y. Of course, you can always calculate the correlation coefficient, but you can see the correlation from a graph. An x-y graph that shows a positive trend (slope positive) indicates a positive correlation. An x-y graph that shows a negative trend (slope negative) indicates a negative correlation.
What are the disadvantages of a scatter graph?
A scatter graph may use a positive correlation or negative correlation, to shows points of the graph in either a dipping or climbing line, and is fairly easy to read the data. A zero correlation is when the points are scattered across the graph and this can make seeing the data difficult. It's a bit like "dot to dot" in a children's puzzle book, but without the numbers at the side of the dots!
Which graph shows a positive correlation between x and y?
Any graph where, from left to right, the slope goes upward (assuming the axes are labelled in the standard way).
What is a purpose of a scatter graph?
By finding a correlation trend by means of line of best fit.
What graphs can you use to measure correlation?
A scatter graph can be used to establish whether or not there is correlation and to get an approximate idea as to its strength. But no graph will actually measure correlation.
What is a correlation statement?
a correlation statement is a sentence that says whether the points on a scatterplot have a positive, negative or no correlation.ex. This graph shows a negative correlation, as the number of cows increases (x axis data) the profitability decreases (y axis data).
What graph best shows how different items compare to each other?
a bar graph
What Best graph for growth of lizard?
Line graph because it shows change over time.
A graph is best used to display data that shows a change over time?
A line graph.
What type of graph best shows how something changes over a period of time?
A line graph shows change over a period of time.
How do you know when there is positive correlation on a graph?
when the points on the graph are close to each other;)
