Question

3 why are pictographs most helpful for a rough estimate of amounts instead of exact numerical data? pictographs use symbols and/or partial symbols. pictographs use only whole symbols. symbols do not convert directly to numerical values. pictographs are more accurate than circle graphs. skip 2/10 complete

Explanation:

To determine the correct answer, we analyze each option:

• Option 1: Pictographs use symbols (and partial symbols) to represent quantities. Since partial symbols can be used, they are better for rough estimates (as exact conversion to numbers might not be straightforward) rather than exact numerical data.
• Option 2: Pictographs can use partial symbols, so "only whole symbols" is incorrect.
• Option 3: Symbols in pictographs do convert to numerical values (each symbol represents a certain quantity), so this is wrong.
• Option 4: Pictographs are not more accurate than circle graphs (which show proportions precisely); this statement is false.

Answer:

A. Pictographs use symbols and/or partial symbols.
