What does the slope of a trend line tell you about the relationship between two quantities?
If the slope of the trend line between variables X and Y is m, then an increase in value of 1 unit in X is associated with an increase of m units in the value of Y. The relationship is one of association, not of cause-and-effect.
What is the difference between a trend line and a line of best fit?
Oh, honey, let me break it down for you. A trend line is a general direction showing the overall trend of data points, while a line of best fit is a specific line that minimizes the distance between the line and the data points. So basically, a trend line is like a rough sketch, and a line of best fit is like the tailor-made suit that hugs those data points just right.
What is true when drawing a trend line for a series of data on a scatter plot?
Based on the information given in the question, nothing particularly is true. The line need not be straight, or even a smooth curve. There need not be any points on the line but there need not be any points not on it.
Does a trend line always pass through every point on a scatter plot?
No, that would be quite unusual if if did, although not impossible.
What is the definition of linear equation?
A linear equation has a constant rate of change, or slope (change in y (dependent) value over change in x (independent) value), when graphed forms a straight trend line, and is in the format y=mx+b (y is dependent value, m is slope, x is independent value, and b is the y-intercept (the value of y when x=0).
What is a slope'?
A smooth line drawn between points on a graph to reflect the general trend.
Which is the equation of a trend line that passes through the points (3 95) and (11 12) Round values to the nearest ten-thousandths.?
Y=_10.35x+126.125
What is a trend on a graph?
It is the description of a slope of a line which connects from many points you mark to show a way that your graph data may increase or decrease. If it is decreasing, you have a downwards trend. If it is increasing, you have an upwards trend.
What is Name of slant on a line graph?
The name of the slant on a line graph is called the slope. The slope represents the rate of change between two points on the graph and is calculated by dividing the change in the y-coordinates by the change in the x-coordinates. A positive slope indicates an upward trend, while a negative slope indicates a downward trend.
When finding the slope of the trend line what does the slope mean about the data of the scatterplot?
The slope of the trend line is the rate of change of the data. It is the ratio of the change of the dependent variable to the rate of change of the independent variable. Slope represents the value of the correlation.
What is the slope of a trend line?
It is the rise/run for the line.
Why is determination of density by the slope method generally more accurate than a from individual data points?
The determination of density by the slope method is generally more accurate because it involves finding the slope of a linear relationship between mass and volume, which reduces the effect of random errors in individual data points. This method is based on multiple data points and takes into account the overall trend in the data, leading to a more precise calculation of density.
What does a trend mean on a line graph?
It is a description of the Slope of the line with respect to the two variables you are plotting. In Statistics, you may be plotting AGE versus Car Mileage and a line drawn through the data is the Trend Line.
What does trend mean you math terms?
A trend is a math term. It is on a line graph. It is a slope between two variables.
If solving for the slope of the best fit line it is a good choice to choose the points closest to the line or points on the line. True False?
False. When solving for the slope of the best fit line, you should consider all data points in your dataset to find the line that best fits the overall trend. Choosing points closest to the line or on the line may bias your results and not accurately represent the relationship between the variables.
What is the shape of a graph of a linear function?
The graph of a linear function is a straight line. It can have a positive slope, indicating an upward trend, or a negative slope, indicating a downward trend. The line can also be horizontal if the function has a slope of zero, representing a constant value. The overall shape is determined by the function's slope and y-intercept.
How do you find the trend on a line graph?
it is a description of the Slope of the line with respect to the two variables you are plotting. In Statistics, you may be plotting AGE versus Car Mileage and a line drawn through the data is the Trend Line.http://wiki.answers.com/What_does_a_trend_mean_on_a_line_graph#ixzz18qYakrsc
