A group of 10 students participated in a quiz competition. Their scores are shown below: 4, 4, 3, 4, 3, 12, 4, 3, 2, 3 Part A: Would a dot plot, a histogram, or a box plot best represent the data shown above if the purpose of the graph is to highlight the frequency of each individual score? Explain your answer. (4 points) Part B: Provide a step-by-step description of how you would create the graph named in Part A. (6 points)
The box plot below shows the total amount of time, in minutes, the students of a class surf the Internet every day: A box plot is shown. The left-most point on the plot is 20 and the right-most point is 95. The box is labeled 40 on the left edge and 60 on the right edge. A vertical line is drawn inside the rectangle at the point 50. Part A: List two pieces of information that are provided by the graph and one piece of information that is not provided by the graph. (4 points) Part B: Calculate the interquartile range of the data, and explain in a sentence or two what it represents. (4 points) Part C: Explain what affect, if any, there will be if an outlier is present. (2 points)

Step-by-step explanation:
Colour is used in map because it give the map a good look and also provide definite information. Different colours are used to indicate specific features on the map. For example

Chemicalchanges:
The changes in which the substance loss their properties because it can't be reversed for eg. burning of wood. In this changes new substance formed. It is also called irreversible changes.
Answer:
Two plots which are commonly used to visualize all the distribution of values in a datasets are dot plots and histograms.
A dot plot displays individual data values along the x-axis and uses dots to represent the frequencies of each of the individual value.
A histogram displays data ranges alongside the x-axis and uses rectangular bars to represent the frequency of values that fall into each range.
The x-axis shows the individual data values and the y-axis shows the frequency of each value.
For example, we can see the value “2” occurs three times in the dataset because there are three dots above it. Similarly, we can see that the value “3” occurs just once because there is only one dot above it.
The x-axis shows ranges of values (0-2, 2-4, 4-6, 6-8 , 8-10) and the y-axis uses rectangular bars to represent the frequency of individual values in the dataset that fall into each range.
For example, we can see that seven values are between 0 and 2, two values are between 2 and 4, and so on.
