Introduction to Bar Graphs

The video tutorial by Mighty Owl guides students through creating and analyzing picture and bar graphs. It begins with a nature walk scenario where kids choose different hiking trails, leading to the creation of a picture graph. The tutorial then introduces bar graphs, comparing them to picture graphs, and explains how to create both horizontal and vertical bar graphs using data from animal footprints. The video concludes with an analysis of bar graphs, highlighting the importance of labels, numbers, and spacing, and correcting errors in a student's graph.

What is the main difference between a picture graph and a bar graph?

• A picture graph is always vertical, while a bar graph is horizontal.

• A picture graph has numbers, while a bar graph does not.

• A picture graph is more colorful than a bar graph.

• A picture graph uses symbols, while a bar graph uses bars.

In a bar graph, what does the length of the bar represent?

• The type of data

• The amount of data

• The shape of the data

• The color of the data

When creating a vertical bar graph, where do the bars start?

• At the top and go down

• At the side and go across

• At the bottom and go up

• In the middle and go sideways

What is the vertical axis label in the animal footprint bar graph?

• Animal types

• Footprint types

• Number of footprints

• Trail names

What was the animal with the least number of footprints found?

• Deer

• Raccoon

• Bear

• Moose

What label should Eric add to the horizontal axis of his bar graph?

• Votes

• Animals

• Birds

What is one feature that Eric's bar graph was missing?
