Understanding Time Series Graphs

This video tutorial explains what a time series graph is and how to construct one. It covers the steps to create a graph using data points over time, including labeling axes, plotting points, and drawing lines. The video also discusses analyzing the graph by examining slopes to identify growth or decline periods and comparing multiple data sets.

What is the primary purpose of a time series graph?

• To calculate the average of data points

• To display data in a pie chart format

• To compare different types of data

• To show data points over a period of time

What should be labeled on the x-axis when constructing a time series graph for monthly data?

• Months

• Weeks

• Years

• Days

When marking the y-axis for video views, what should the values be labeled as?

• Video views in hundreds

• Video views in thousands

• Video views in tens

• Video views in millions

What is the first step in plotting data points on a time series graph?

• Finding the point of intersection for each data pair

• Drawing a line through all points

• Labeling the graph

• Calculating the average of the data

What is the final step in completing a time series graph?

• Drawing a line from point to point

• Calculating the total views

• Labeling the axes

• Finding the average slope

What does a steep slope on a time series graph indicate?

• A period of decline

• A period of no change

• A period of major growth

• A period of stability

How can you compare two different data sets on the same time series graph?

• By using a bar chart

• By plotting them on separate graphs

• By using the same line style for both

• By using different colors for each line
