Question

Explain what you can tell just by comparing the symbols in a picture graph

Answer 1

The correct answer is:

What objects we're comparing.

Explanation:

In a picture graph, symbols are used to represent the data being displayed. For example, if we took a survey on the types of foods people preferred at a cookout, we could use a picture of a hamburger, a picture of a hot dot and a picture of a chicken leg.

We cannot tell anything about the amounts in the graphs just by comparing the symbols.

Answer 2

Suppose there are two car manufacturing company, which produces two different cars.The number of cars manufactured monthly is,

→Company A →→→→40      40     50      60       60      70     80      90    50    30   120  200

→Company B→→→→→20      30       40      50      60      80      80     100   100  120    140    180

So, if 10 cars manufactured is represented by symbol →Δ

Company A→→ΔΔΔΔ    ΔΔΔΔ    ΔΔΔΔΔ   ΔΔΔΔΔΔ    ΔΔΔΔΔΔ    ΔΔΔΔΔΔΔ   ΔΔΔΔΔΔΔΔ      ΔΔΔΔΔΔΔΔΔ    ΔΔΔΔΔ   ΔΔΔ     ΔΔΔΔΔΔΔΔΔΔΔΔ    ΔΔΔΔΔΔΔΔΔΔΔΔΔΔΔΔΔΔΔΔ

Company B→→ΔΔ    ΔΔΔ    ΔΔΔΔ   ΔΔΔΔΔ   ΔΔΔΔΔΔ    ΔΔΔΔΔΔΔΔ        ΔΔΔΔΔΔΔΔ        ΔΔΔΔΔΔΔΔΔΔ     ΔΔΔΔΔΔΔΔΔΔ     ΔΔΔΔΔΔΔΔΔΔΔΔ       ΔΔΔΔΔΔΔΔΔΔΔΔΔΔ      ΔΔΔΔΔΔΔΔΔΔΔΔΔΔΔΔΔΔ

By looking at the Symbols we can compare easily, which company has manufactured more cars if we have represented through tally marks.

By looking at the pictures  answering becomes easier.

Now, a days tally marks is used , but if data values are high, we use symbols, so our work that is representation of thing becomes easier on the graph.
