A) Draw a pie chart that represents the two types of lung cancer. Show your working.

Answer:

<em>Please, check the image provided</em>

Explanation:

<u>Pie Charts</u>

They are graphic representations of quantitative results from experimental or theoretical experiences. Instead of showing a table, it's usually preferred to show a graph where the viewer can easily understand the relative relations between the parameters under study.

The chart pie is a circular shape divided into sectors whose areas are proportional to the proportions between each parameter and the total. Since the whole sector of a circle has 360°, each sector will be a proportion or ratio of that angle.

The outcome shown in the table gives us these statistics:

Small Cell Carcinoma : 15%

Non-Small Cell Carcinoma : 85%

Each category has the following angles in the chart pie

Small Cell Carcinoma : 15%*360°=54°

Non-Small Cell Carcinoma : 85%*360°=306°

The first category is shown in blue and the second in green. Please check the image below.

Descriptive investigations involve collecting data about a system, but not making observations .
Angelina_Jolie [31]
The correct statement should be: Descriptive investigations involve collecting data about a system, but not making comparisons. 
so i believe the statement above is false

In descriptive investigations, we shall not make any hypothesis for the situation and we just need to fully record all obeservations.
By doing this, we could fully analyze the variables without comparing and manipulating it.
