1 | 2 |

2 | 3 |

3 | 3 |

4 | 2 |

5 | 4 |

Step: 1

The line plot is a representation of the data on a number line, where each unique data value is a point on the line and the number of times it occurs in the set is indicated by crosses over its position on the number line.

Step: 2

From the frequency table, a list of the unique data values can be obtained and the frequency column gives the number of times each value occurs in the data set.

Step: 3

Plot this data with numbers 1-5 on the number line. Put the number of crosses over the values to indicate frequency / repeated occurrence.

Step: 4

Observing the choices, the number of occurrences of each data value match with the number of cross symbols in the Figure 3.
