A data set is considered proportional when there is a constant ratio between two variables, meaning that as one variable increases or decreases, the other variable changes at a consistent rate. This can be represented mathematically as ( y = kx ), where ( k ) is the constant of proportionality. In a graphical representation, proportional data will create a straight line that passes through the origin (0,0).
What else can I help you with?
What describes the relationship between one set of data that increases as another set of data increases. This is synonymous with directly related?
The relationship where one set of data increases as another set of data also increases is described as a positive correlation. In this context, the two variables move in the same direction, meaning that higher values of one variable correspond to higher values of the other. This is often referred to as being directly related or directly proportional, indicating a consistent and predictable relationship between the two sets of data.
What is set of data?
A set of data is a set of nuumbers .
How do you tell if a table is proportional?
A table is proportional if the ratio of the values in one column to the values in another column remains constant across all pairs of data. To determine this, you can calculate the ratio for each pair of corresponding values and check if they are all equal. If the ratios are consistent, the relationship is proportional; if not, it is not proportional. Additionally, plotting the data on a graph should yield a straight line through the origin if the relationship is proportional.
Is 7 and 9 proportional?
You CAN'T determine whether two numbers are proportional, just by looking at one number from each set.
What is the effect of the a small outlier value Will it affect of a data set?
No. The data set will remain the data set: they are the observations that are recorded.

What is a bar gragh?
.)A graph consisting of parallel, usually vertical bars or rectangles with lengths proportional to the frequency with which specified quantities occur in a set of data. Also called bar chart

How cost effective is a database system?
This is proportional to the intrinsic value of the data, need and method for accesing such data, and the need to keep data organized.
Is 7 and 9 proportional?

How do you determine whether a relationship shown in a table is a proportional relationship?
A proportional relationship is of the form y = kx where k is a constant. This can be rearranged to give: y = kx → k = y/x If the relationship in a table between to variables is a proportional one, then divide the elements of one column by the corresponding elements of the other column; if the result of each division is the same value, then the data is in a proportional relationship. If the data in the table is measured data, then the data is likely to be rounded, so the divisions also need to be rounded (to the appropriate degree).
If the coefficient of determination for the data set is 0.75 and the SSE for the data set is 13 what is the SST for the data set?
It is 52.
How Do You describe the shape of a data set?
You describe the shape, not of the data set, but of its density function.You describe the shape, not of the data set, but of its density function.You describe the shape, not of the data set, but of its density function.You describe the shape, not of the data set, but of its density function.
What is median in the set of data?
The median in a set of data, would be the middle item of the data string... such as: 1,2,3,4,5,6,7 the Median of this set of data would be: 4
What is the effect of the a small outlier value Will it affect of a data set?
No. The data set will remain the data set: they are the observations that are recorded.
If data set A has a larger standard deviation than data set B data set A is more spread out than data set B.?
Yes, if data set A has a larger standard deviation than data set B, it indicates that the values in data set A are more spread out around the mean compared to those in data set B. A higher standard deviation signifies greater variability and dispersion in the data. Conversely, a smaller standard deviation in data set B suggests that its values are more closely clustered around the mean.
