Scatter Plots on TI-84

Created by:MICHAEL HARRISON

Name three things you learned from this youtube video:

1)it didnt teach me nothin

2)how to plug the numbers in

3)how to plot it on a graph

Now answer the following questions. Post a link that you used to help you research it.
1) What is a scatter plot?

A scatter plot is a type of mathematical diagram

2) What is a line of best fit?

is a straight line that best represents the data on a scatter plot.

3) What is a curve of best fit?

Curve fitting is the process of constructing a curve,

4) Name 2 examples where scatter plots are used in real life:

construction, people who like math

5) Write an equation of a best fit line for the following scatter plot:

(3,9)(5,8)

-At 11 units, what is a good prediction for amount of minutes?

idk

6) Find a scatterplot problem, paste it in here and give the answer.
Student Number

y=16x+34

Name three things you learned from this youtube video:

1)Nothing.

2)How to put data in the scatter plot.

3)Stat:Edit

Now answer the following questions. Post a link that you used to help you research it.
1) What is a scatter plot?

A scatter plot or scattergraph is a type of mathematical diagram using Cartesian coordinates to display values for two variables for a set of data.

2) What is a line of best fit?

A line of best fit (or "trend" line) is a straight line that best represents the data on a scatter plot.
This line may pass through some of the points, none of the points, or all of the points.

3) What is a curve of best fit?

Curve fitting is the process of constructing a curve, or mathematical function, that has the best fit to a series of data points, possibly subject to constraints

4) Name 2 examples where scatter plots are used in real life:

For math majors, and whoever enjoys math.

5) Write an equation of a best fit line for the following scatter plot:

(4,60) (7,80)

-At 11 units, what is a good prediction for amount of minutes?

I dunno.

6) Find a scatterplot problem, paste it in here and give the answer.
Student Number

m = (80-60) / (7-4)
m = 20 / 3
m = 20/3

y = mx + b
y = 20/3x + b
60 = (20/3)4 + b
60 = 80/3 + b
100/3 = b

Thus a best fit equation is:
y = 20/3x + 100/3

Name three things you learned from this youtube video:
1)It wasnt boring like most of the other videos.

2)Shows many other ways to solve the scatter plot.

3)It wasnt like most of the other videos, it showed that math can be kind of fun.

Now answer the following questions. Post a link that you used to help you research it.
1) What is a scatter plot? A scatter plot is a graph that has many dots that show a line.

2) What is a line of best fit? A line that goes through most of the dots on the graph.

3) What is a curve of best fit? When the a line that curves through the scatter plot.

4) Name 2 examples where scatter plots are used in real life: science
