A histogram is better for "discrete" data and a frequency polygon is better for "continuous" data.
<h3>What is histogram?</h3>
A histogram is a data representation that looks like a bar graph and buckets a wide range of categories into columns all along horizontal x-axis.
- The numeric count or percentage of happenings in the data for every column is represented by the vertical y-axis.
- Columns can be employed to visualize data distribution patterns.
- Technical analysts use the MACD histogram in trading to making data in momentum.
- The MACD histogram columns could provide buy and sell signals earlier than the MACD and signal lines.
<h3>What is
frequency polygon?</h3>
Frequency polygons are a graphs depiction of the distribution that aids in data comprehension by utilizing a specific shape.
- Frequency polygons are comparable to histograms but are more beneficial when comparing two or more different data sets.
- The graph primarily displays cumulative frequency distribution data as a line graph.
- Frequency Polygons are a type of graph that deciphers information or data and are broadly used in statistics.
- This graphic form of data representation aids in the depiction of the data's shape and trend in a systematic and organized manner.

Answer:
£103.70
Step-by-step explanation:
Payment per hour = £8.50
Overtime payment = 1.4 × 8.50
= £11.90
Ben worked for 11 hours.
Normal time = 8 hours
Overtime = 3 hours
Total earnings = (8 hours × 8.50) + (3 hours × 11.90)
= £68 + £35.7
= £103.70
Ben earned £103.70 for working for 11 hours
A is correct :)
Hope this helps!
