Why do we make graphs to represent data or information?

Graphs help us to understand data better and help us answer questions about the data.

What are the different parts of a bar graph?

Bar graphs have a title, labels for categories, numbers or tick marks on one axis.

What are the different parts of a pictograph?

Pictographs have a title, labels for categories, a key or legend.

What part of a bar graph helps us answer questions such as 'how many more' or 'how many less' one category has than another category?

The heights of the bars and the value that represents help us make comparisons among the different categories.

How are bar graphs and pictographs alike?

Both help organize and represent data on a chart and help us solve problems by looking at the graph.

Why do we use scaled bar graphs and scaled pictographs, instead of bar graphs and pictographs that use single units?

Scaled graphs allow us to create graphs from data where larger numbers are involved. They are easier to read.

How do scaled bar graphs and scaled pictographs differ from graphs that use single units?

On a scaled bar graph the intervals between tick marks represent units greater than one, and on scaled pictographs, each picture or image represents more than one item.

In the video, what information did Marcos and April use to help them choose a scale to use to make a bar graph for the food bank items?

The greatest number of items they wanted to graph was 48 cartons of milk, so they chose a scale of 5.

In a scaled pictograph, what does a part of a picture or part of an image represent?

Part of a picture or part of an image represents a number that is smaller than the scale unit.

In the video, according to Adesina, do we always need to know the exact amount a bar or picture category represents on our graph? Why or why not?

No, we do not always need to know the exact amount when we are making comparisons between categories. Looking at the heights of the bars or the number of pictures in each category compared to other categories helps us answer the questions "which category has more" and "which category has fewer".
