Distribution of the Data

For this task, we'll look at US Census data for growth in the Hispanic (Latino) population between 2000 and 2010.

Part A

Look at the state data in the Number column. create ahistogramof the data.(You can copy a column of data from the spreadsheet and paste it into the histogram tool.) Scale and label the histogram appropriately.Export an image of this histogram, and insert it below.

Growth in the Hispanic (Latino) Population in the United States Since 2000

Next we'll look at US Census data for growth in the Hispanic (Latino) population between 2000 and 2010.Before looking at the data, make some predictions:

Which state(s) do you think would have experienced the greatest amount of growth in the Hispanic (Latino) population?Why do you think that?

Will the states with the biggest growth in numbers of Hispanics (Latinos) also be the states with the biggest percentage increase?Why or why not?

Now open thespreadsheetagain and look at the columns under the heading Population Change 2000 to 2010.

Part A

Make ahistogramof the data in the Percent column for the states.(You can copy a column of data from the spreadsheet and paste it into the histogram tool.) Set useful limits and intervals and label the histogram appropriately.Export an image of the histogram, and insert it below.

Part BGenerate abox plotof the data in the Percent column.Label the box plot, export an image of it, and insert the image below.

Part CSome states experienced growth of more than 100% in their Hispanic (Latino) population between 2000 and 2010.What does it mean for a population to grow by more than 100%?

Part DHow do the spread, shape, and skewness of this data compare with those of the previous data you explored?

Part ECheck the Exclude Outliers box, and click the Update button.How many outliers do there appear to be?Using the mathematical definition provided in task 1f, calculate the minimum and maximum limits of this box plot.Based on those limits, what states are considered outliers here?Describe the differences between the outliers in this data set and the outliers in the data set for task 1.

Part FAre the same states outliers in this data set and in the previous data set?Why or why not?

Part GWhich data set, Number or Percent, would you use to best describe the growth of the Hispanic population in the United States?Why would you choose this set?

Part HDescribe a situation in which it might be beneficial to use the other set of data (the set that you didn't choose in the question above) to describe the growth of the Hispanic population.

The Number of Hispanics (Latinos) in the United States

Consider the population of Hispanic (Latino) people in the United States, according to the 2010 US Census.Look at the data in thisspreadsheet.Examine the data for the 2010 US Census.

In addition look at these resources before you move on to the task:

US Census data

US Census regions

Part A

How do the columns titled Number and % of Total Population relate to the column titled Total?

Part B

Make ahistogramof the state data in the column titled % of Total Population.(If you need help, follow theseinstructionsfor using the online probability tools.Note that you can copy a column of data from the spreadsheet and paste it into the histogram tool.) Set useful limits and intervals and label the histogram appropriately.Export an image of the histogram, and insert it below.

Part F

Return to the Box Plot tool, click the Exclude Outliers checkbox, and then click Update.The plot boundaries contract, with outlier data points showing beyond the whiskers of the plot.Outliers are generally considered to be points that are more than 1.5 (interquartile range) below Q1 or above Q3.What are the minimum and maximum values for the box plot once you exclude outliers?Based on your box plot, how many outliers do you have?

Part G

Which states are represented by the outlier data?What do these states have in common that might contribute to making them outliers?

Part H

According to the US Census data, the Hispanic (Latino) population of the United States as a whole is 16.3% of the total 2010 US population (as shown in cell G5).Where would this percentage fit into the list of the distribution of the individual states on your latest box plot?Does it seem surprising that it would fit there?How might you explain this situation?
