Question

Questions to answer: 2.1 State the advantages and disadvantages of dot plots, stem plots, and histograms. It may be helpful to make a chart. 2.2 Suppose I have three sets of data: • I want to display the test scores of 25 students in my class. The scores range from 50 to 95. • I want to display the number of siblings my 25 students have. The data ranges from no siblings to 5. • I want to display the transcript averages of 300 students in the school. The scores range from 55 to 100. One set of data will be shown using a dot plot. One set using a stem plot, and one set using a histogram. Explain which data set should go with each type of graph. Topic: Describing Graphs Please watch 1.6: Daily video from College Board Questions to answer: 2.3 When describing a distribution, what are the four characteristics that should be mentioned? 2.4. Take a look at the graph below, which shows the percentage of population in various countries with access to electricity.

Transcript

00:01 So in this question we have to tell the advantages and disadvantages of dot, stem plots and histograms.

00:07 Starting with histogram.

00:11 So advantage number one, that it can be used to display large range of data.

00:15 Advantage two provides a consistent appearance as intervals are always equal, right? that is, it is not very unequal.

00:28 The intervals are equal.

00:30 So it is very consistent in appearance.

00:36 Whereas if intervals were not equal, then it would be of sort which is not very pleasing to see.

00:45 That is, it would be inconsistent in appearance.

00:48 Third advantage, data is easily comparable between intervals as the intervals are equal.

00:56 Now coming to disadvantages, first disadvantage cannot read the exact frequency of a particular observation as data is under interval as data is under intervals, right? so what does this mean? that as the data is in intervals, we have divided the data in intervals.

01:23 So the exact frequency of particular observation cannot be talked about.

01:30 Coming to disadvantage 2, it cannot display categorical data, but it can only display numerical data.

01:37 Coming to third, it can be only used for continuous data.

01:41 It cannot be used for discrete data.

01:43 Coming to stem plots, advantage number one, we can extract the raw values of the data.

01:50 Advantage 2...
