What else can I help you with?
What word best describes the trend on a line graph when the line connecting the points falls from left to right?
A negative correlation.
How can a graph present data in a misleading way?
Yes, just by changing the distance between data points you can make a trend seem to accelerate rapidly and steeply, or do the opposite and hide that information.
What is the difference between a pattern and a trend?
A trend is a certain direction which something is changing. A pattern is where a repeat of a series or trend is seen over and over.
What is the trend on a line graph?
It all depends on what the trend is doing... is it going up, down, or horizontal? If up, it's an up trend If down, it's a down trend If horizontal, it's in a trading range.
What is a line graph trend?
trend is the increasing or decreasing in a line graph Example. If u choose to see number of students in a school and they are getting bigger its trend is increasing
When a trend line is drawn on a scatter-plot there are 4 points above the trend line about how many points should be below the trend line?
The amount an individual point departs from the trend line is the important feature, not that the number above and below should be balanced. A point that is much further away from the trend line is less likely to represent the process being plotted. Each point is of course quite real, but each are influenced by measurement error, random processes within the experiment, recording (transcription) error, and so on. If most of your points lie on a smooth curve, it is more likely that an outlier is subject to error.
True or false in a data plot about half the data points will lie below the line of best fit?
True. In a data plot, the line of best fit represents the average trend of the data. Therefore, approximately half of the data points should lie below the line of best fit and half should lie above it if the data is evenly distributed.
Why isnt it necessary for all of the data points to be on the drawn line of the graph?
The line of a graph is quite often used to indicate the average of various data points that fall both above and below the line. Very jagged lines get smoothed out, but the trend is the same.
What do you notice about the boiling points as you move from left to right across the periodic table?
The trend of boiling points across a period in the periodic table should decrease from metals to nonmetals. The trend becomes more complicated between metals, the boiling point of metals tends to increase across a period.
What is the general trend of the melting points of elements on the periodic table?
The general trend of melting points of elements on the periodic table increases from left to right across a period and decreases down a group.
What do you mean by mean vector in statistics?
The direction in which the trend analysis points.
What is a trend on a scatter graph?
Its when the datas points are going upwards or downwards
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.
How can you predict the placement of an unknown element on a periodic table based on physical an chemical properties?
You look at trends. An element is likely to have properties somewhere between the element above it and the element below it; if there's nothing below it (or above it), then you can follow the general trend up (or down) that column and extrapolate.
When does a scatterplot show a correlation?
A scatterplot shows a correlation when there is a discernible pattern or trend in the points plotted on the graph. This can be a positive correlation, where points trend upwards, indicating that as one variable increases, the other does too; or a negative correlation, where points trend downwards, indicating that as one variable increases, the other decreases. If the points are randomly scattered without any clear pattern, it suggests little to no correlation. The strength of the correlation can be assessed visually or quantified using correlation coefficients.
What type of correlation does the scatter graph show?
To determine the type of correlation shown in a scatter graph, you would typically look at the pattern of the plotted points. If the points trend upwards from left to right, it indicates a positive correlation. Conversely, if the points trend downwards, it suggests a negative correlation. If the points are scattered without any discernible pattern, it indicates little to no correlation.
What word best descibes the trend on a line connecting the points falls from left to right?
decreasing
