What mistake did Jayla make while creating a stem and leaf chart
Answer:
Option 3. She forgot the 7 in her stem
Step-by-step explanation:
[ Take a look at the attached picture. ]
- While creating stem and leaf plot, one must write the numbers from the beginning to the end one by one in the stem, even if a number's leaf count is zero.
- Commas aren't necessary but writing them is not incorrect.
- If a number exists twice or more times, we have to write them as many times as given.
