Question description

How did the final temperature of the hot water alone
is the best time to add it so that you have the warmest possible coffee after
Answer: The final temperature of water did not vary
greatly with the others. However the temperature of hot water alone was
52.5 °C at the end which was hotter
than the other two trials which was 51 °C for the trial where cold water was added after 2 minutes and 50 °C
for when cold water was added at the 12th hot water.
When taking a look at my data table and my graph you can actually have
two conclusions. In the case when cold water was added to the hot water at the
12th minute, the hot water had cooled down already since it was left
for 12 minutes so the cold water did not affect the content in the cup greatly.
Therefore I think its best to add the cream after the 2nd minute.
Even though the content in the cup cools down suddenly, when looking at it
overall the content in the cup that water was added to after 2 minutes (51°C)
is warmer than the cup where water was added after 12 minutes (50°C). Considering
the fact that we are going to add a gold substance we should be expecting a
drop in temperature.
How might you describe the cooling curve for the hot
water alone? Was it linear or nonlinear? How about the cooling curve for the
other trials?
Answer: The curve that is plotted for the hot water
alone is a leaner line, as the line we can see is a smooth straight line. When
looking at the graph we can see that the physical entities (time and
temperature) are inversely proportional to each other. it shows us the one
entity increases (time) as the other decreases (temperature ) .
The curve plotted for the hot water when cold was
added and 2mins and 12mins could be described as an inverse tend line or
nonlinear. This is due to the sudden adding of cold water onto the hot water,
which makes the temperature and time have an inverse relationship.
Name three different kinds of graphs that
are often used to plot information and discuss the value of each.
Answer: There are many different kinds of graphs that
we can use in order to plot information. A bar graph, which can  be either vertical or horizontal. Either
numerical or categorical variables are labeled on axis x and axis y. According
to the values, the bar’s height will be scaled. It is possible to compare data
about the same thing or location if a bar graph is drawn in a 3-dimensional
way. The bars in a bar graph are to be arranged in the order of frequency in
order for the more important categories to be emphasized.
Another kind of graph is the pie
chart. Every section of a pie graph is a data percentage, and according to the
size of the percentage, a bigger or a smaller portion is covered. The segments
are arranged clockwise, from biggest to smallest. Pie charts are very useful as
they are easily comprehensible by the viewer, it is a way to compare subjects
in the form of percentages.
Another example of a graph is the
scatterplot. Scatterplots are used in order to pair data by using the y axis
and the x axis. In order to show trends on a scatterplot graph, correlation and
regression are used. In order to analyze the data, by using a scatterplot we
are able to compare the variables, two at a time. A scatterplot is a graph
which we use in order to plot the points for two variables.
Explain what chart junk is and how it
differs from the kind of items you should include in your graphs. Provide four examples.

Answer: Chart junk can be defined as the unneeded,
excess and confusing elements found in graphs. The markings on a graph can be
classified as chart junk if they do not belong to the minimum set of visuals
needed to deliver clear information to the viewers. The kind of items we should include in our graphs differs a lot from
chart junk. We have to firstly specify the units we are using. If we are to
plot a quantity which does not have units, we must omit the parenthesis with
the unit symbol from the axis.
