Sketch A Scatter Plot

Section 1.1
Question 16

Sketch a scatter plot of the data
shown in the table.

See attachment.

The idea here is to plot the x and y values on the xy-plane.

What is the main goal of a scatter plot?
Is this not a statistics lesson? Why would it be in Section 1.1 in a precalculus book?

Scatter plots' primary uses are to observe and show relationships between two numeric variables. The dots in a scatter plot not only report the values of individual data points, but also patterns when the data are taken as a whole. Identification of correlational relationships are common with scatter plots.

this is your scatter plot

I am correct in terms of plotting points, right?
However, points are not connected with a smooth curve or a line. Scatter plots do not form a function, right?

 

[MathLover1]

no, they do not form a function but you can find a function that fit this graph

A scatter plots can describe relationships between variables in many ways: positive or negative, strong or weak, linear or nonlinear.
A scatter plot can also be useful for identifying other patterns in data. We can divide data points into groups based on how closely sets of points cluster together. Scatter plots can also show if there are any unexpected gaps in the data and if there are any outlier points. This can be useful if we want to segment the data into different parts, like in the development of user personas.

I was right. Mathematics is found throughout life, in all fields of study.
