Draw a frequency polygon Frequency diagramFrequency polygonModal class Estimated rangeMid-point Draw and interpret a frequency polygon Keywords Is for you to answer: The table shows the age distribution of people at the Bowls. Draw a frequency polygon Is for you to answer: Compare the ages of the people in the two clubs. Level 7 Level 8 Age, a, yearsFreq 0 ≤ a < ≤ a < ≤ a < ≤ a < ≤ a < 505 Age, a, yearsFreq 20 ≤ a < ≤ a < ≤ a < ≤ a < ≤ a < 7024

Frequency Polygons Intro: 03/03/2019 We can put large quantities of continuous data into a grouped frequency table. A grouped frequency table does not tell you the actual data values so you can only find estimates of the averages. 5 < t ≤ 10 This could mean a group of data where time is greater than 5, and less than and equal to 10.

Frequency Polygons 03/03/2019 Starter: Find the midpoints for each of these classes. a)10 < a ≤ 20 b)85 < a ≤ 90 c)120 < a ≤ 140 d)1000 < a ≤ 2000 e)30 < a ≤ 60 f)1 < a ≤ 2 g)5 < a ≤

Frequency Polygons Intro: 03/03/2019 You can represent grouped data in a frequency polygon. To draw a frequency polygon for continuous data you plot the midpoint of each class interval against the frequency.

Example: The tables show the ages of the first 100 people attending concerts to see the bands U2 and The Killers. Age a years Freq. 10 < a ≤ < a ≤ < a ≤ < a ≤ 5020 Mid Point The Killers Age a years Freq. 20 < a ≤ < a ≤ < a ≤ < a ≤ 6020 Mid Point U2 The Killers U2 Key The modal age is greater for U2 than The Killers. This tells us that there is a older crowd at the U2 concert.
