Put the \(X\) variable on the horizontal axis and the \(Y\) variable on the vertical axis. $$ \begin{array}{llllll} \hline X & 3 & 5 & 2 & 7 & 6 \\ \hline Y & 1 & 2 & 1.5 & 3 & 2.5 \\ \hline \end{array} $$

Short Answer

Expert verified
The graph would have points plotted at the following coordinates: (3, 1), (5, 2), (2, 1.5), (7, 3), (6, 2.5).

Step by step solution

01

Identify Values

Examine the provided table. For each X value in the first row there is a corresponding Y value in the second row. Identify these value pairs: (3, 1), (5, 2), (2, 1.5), (7, 3), (6, 2.5).
02

Plotting X Values

Move on to the graph paper. The X values (the horizontal values) are 3, 5, 2, 7, 6. Identify these numbers on the x-axis and mark potins above these values.
03

Plotting Y Values

Now, plot the corresponding Y values (the vertical values) for each of the marked X values. These are 1, 2, 1.5, 3, 2.5 respectively. Each pair (x, y) represents a point on the graph. Mark the points on the graph: (3, 1), (5, 2), (2, 1.5), (7, 3), (6, 2.5).
04

Plot Completion

Once all the points are successfully plotted, you will have a visual representation of the relationship between X and Y based on the initial table data.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Plotting Data
Plotting data is a fundamental skill in statistics for visualizing the relationship between variables. In the given exercise, we learned how to plot the coordinates on a scatter plot by taking pairs of values from two lists corresponding to the X and Y axes. Starting with identifying value pairs, such as (3, 1) and (5, 2), from an ordered list, we then move to representing these data points on a graph.

For clarity, always place each coordinate properly by first locating the X value on the horizontal axis, which will be your starting point. From there, move vertically to the Y value, which is the second number in the pair. Each point is represented by a dot at the intersection of these two values. Ensuring accurate plotting is crucial for the correct interpretation of data, so take your time when marking each point.
Bivariate Data Analysis
Bivariate data analysis involves exploring the relationship between two sets of data. Each set is represented by a variable, usually labeled X and Y. When creating a scatter plot, these variables allow us to analyze how they correlate with each other—whether there's a positive, negative, or no apparent correlation.

In the provided solution, we see a simple representation of bivariate data analysis in action. After plotting the data, we can observe the pattern that the points follow and start to draw conclusions about the relationship. For instance, if the points slope upwards from left to right, this suggests a positive relationship; if downwards, a negative relationship. Identifying the pattern is just the beginning, as we can then proceed to apply mathematical models, like line fitting, to further understand the dynamics between the X and Y variables.
Graphical Representation of Data
The graphical representation of data is a cornerstone of statistical analysis and aids in making complex data comprehensible. A scatter plot is one type of graph used frequently to display the relationship between two numerical variables. The key is to represent data points in a two-dimensional plane which offers immediate visual insights.

Through the scatter plot created in our exercise, we can analyze trends, clusters, and outliers at a glance. Beyond just plotting points, adding elements like a line of best fit or dividing the graph into quadrants can enhance interpretation. One essential tip to remember is that the graph should be scaled appropriately to cover the entire range of data without distorting the visual representation.
Statistics Education
Statistics education equips students with the skills to collect, analyze, and interpret data. A firm understanding of concepts like plotting data on scatter plots, as covered in this exercise, lays the foundation for more advanced statistical techniques. The goal is to make students confident in working with numerical information and translating it into actionable insights.

While working through the steps to plot data, remember that the journey is as important as the destination. Taking the time to comprehend how each point is derived and what it represents reinforces learning. An interactive and participative approach to statistics education helps demystify data analysis and empowers students to harness the power of data in real-world scenarios. Encouraging curiosity and providing clear, step-by-step guidance promotes a deeper understanding and retention of the material.

Does It Pay to Get a College Degree? In Exercise 2.21 on page \(58,\) we saw that those with a college degree were much more likely to be employed. The same article also gives statistics on earnings in the US in 2009 by education level. The median weekly earnings for high school graduates with no college degree was \(\$ 626,\) while the median weekly earnings for college graduates with a bachelor's degree was \(\$ 1025 .\) Give correct notation for and find the difference in medians, using the notation for a median, subscripts to identify the two groups, and a minus sign.

Use the \(95 \%\) rule and the fact that the summary statistics come from a distribution that is symmetric and bell-shaped to find an interval that is expected to contain about \(95 \%\) of the data values. A bell-shaped distribution with mean 200 and standard deviation 25.

Largest and Smallest Standard Deviation Using only the whole numbers 1 through 9 as possible data values, create a dataset with \(n=6\) and \(\bar{x}=5\) and with: (a) Standard deviation as small as possible. (b) Standard deviation as large as possible.

When honeybee scouts find a food source or a nice site for a new home, they communicate the location to the rest of the swarm by doing a "waggle dance." 74 They point in the direction of the site and dance longer for sites farther away. The rest of the bees use the duration of the dance to predict distance to the site. Table 2.32 Duration of \(a\) honeybee waggle dance to indicate distance to the source $$\begin{array}{cc} \hline \text { Distance } & \text { Duration } \\ \hline 200 & 0.40 \\\250 & 0.45 \\ 500 & 0.95 \\\950 & 1.30 \\ 1950 & 2.00 \\\3500 & 3.10 \\\4300 & 4.10 \\\\\hline\end{array}$$ Table 2.32 shows the distance, in meters, and the duration of the dance, in seconds, for seven honeybee scouts. \(^{75}\) This information is also given in HoneybeeWaggle. (a) Which is the explanatory variable? Which is the response variable? (b) Figure 2.70 shows a scatterplot of the data. Does there appear to be a linear trend in the data? If so, is it positive or negative? (c) Use technology to find the correlation between the two variables. (d) Use technology to find the regression line to predict distance from duration. (e) Interpret the slope of the line in context. (f) Predict the distance to the site if a honeybee does a waggle dance lasting 1 second. Lasting 3 seconds.
