TIPS FOR TEACHERS<br />
Lesson 28<br />
●<br />
●<br />
Ensure that learners know the difference between bar graphs and histograms.<br />
The points represented on a broken line graph should not be joined by means<br />
of a continuous solid line. This is because data values between these values<br />
are not known. The points should be joined by a dotted line.<br />

Lesson 29<br />
●<br />
Ensure that learners know that the median will be a number in the data if<br />
the number of data values is odd. If the number of data values is even, the<br />
median will be an insertion into the data set. In this case, the median will be<br />
the average between the two middle values.<br />

Lesson 30<br />
●<br />
●<br />
Ensure that learners know that the median will be a number in the data if<br />
the number of data values is odd. If the number of data values is even, the<br />
median will be an insertion into the data set. In this case, the median will be<br />
the average between the two middle values.<br />
The median is excluded from the lower and upper halves when determining<br />
the lower and upper quartiles.<br />
