STATISTICS

QUESTION ONE

a)

The type of statistical chart used above is histograms. They represent continuous

data where the numbers represented can take any values of number houses in the given range.

However, the first graph, the data has been represented by the frequency of particular phenomena

by using width $50000. It shows selling price that has a range of more than $50000 between

subsequently fixed intervals. The second graph has data represented using categories with a

width of $25000. It shows an interval of $25000 being used in the continuous data to indicate the

range in selling price. In both the first and the second graph, the bars are adjacent to one another.

The histograms are never drawn with spaces between the bars. The data in both graphs

are continuous. Since the first graph has a higher width range, they accumulate a higher number

of homes that are sold and hence they appear bigger compared to the second graph. The second

histogram had precise readings and inferences and give deeper ideas due to its smaller intervals.

Alternatively, the second graph can be said to have used the midpoints of the first graph. The

first graph has used five classes while the second has used eight classes. The maximum selling

price of between 150000-200000 dollars was the highest number with 38 being sold in the first

histogram while the second histogram had 26 houses at the selling prices that range between

175000-200000 dollar ranges.

b)

The number of homes sold for less than S$200000 from both histograms is 42. 38+4

=42 from the first histogram and 4+12+26= 42 from the second histogram.

c)

The number of houses that were sold for a selling price that is less than $200000 will

be added together using figures obtained from the histogram. The added results will then be

divided by the overall house's total that was sold and then the result will be multiplied by 100 to

obtain the percentage as shown below.
