Question

An observation occurring seven times in a data is represented as ______ using tally marks.

Answer 1

An observation occurring seven times in a data is represented as `underline(\cancel(bb|bb|bb|bb|) bb|bb|)` using tally marks.

Explanation:

In tally marks:

• Each vertical line | represents one count.

• Every fifth count is shown as a crossed bundle (four vertical lines with a diagonal slash), written as ||||.

• For seven, you write one bundle of five (||||) plus two more single tallies (||):
  `\cancel(bb|bb|bb|bb|) bb|bb|`
