Graphing Data by Hand

The video tutorial demonstrates how to graph data by hand, focusing on creating a scatterplot. It covers setting up axes, labeling, titling, and using graph paper effectively. The tutorial explains plotting data points and drawing a line of fit to represent data trends. It concludes with a brief introduction to graphing using Excel.

What is the independent variable in the example used in the video?

• Fertilizer amount

• Plant growth

• Time period

• Type of plant

Why is a scatterplot chosen for the graph in the video?

• To display percentages

• To compare categories

• To show a timeline

• To find correlation between two sets of numbers

What should be included in the title of a graph?

• Only the dependent variable

• A brief description of the graph

• Only the independent variable

• Detailed information including variables and context

How should you determine the scale for the x-axis when using graph paper?

• Use random numbers

• Use only whole numbers

• Divide the range by the number of squares

• Start from zero regardless of data

What should you do if your calculated scale results in unwieldy decimal values?

• Start the scale from zero

• Round up to a more manageable number

• Use the decimals as they are

• Ignore the decimals

What is the purpose of a line of fit in a scatterplot?

• To highlight the highest data point

• To represent the average trend of the data

• To separate different data sets

• To connect all data points

Why should you not connect the dots in a scatterplot?

• It is not allowed in any graph

• It is too time-consuming

• The data points represent different entities

• It makes the graph look messy
