Question

The nonprofit group Public Agenda conducted telephone interviews with three randomly selected groups of parents of high-school children. There were 202 black parents, 202 Hispanic parents, and 201 white parents. The sample survey asked the parents to respond to the statement, “A college education has become as important as a high school diploma used to be." Here are the counts of responses:

Write a brief report on the similarities or differences among the three groups of parents in their attitudes towards the importance of a college education. Include a graph or graphs and a test of significance. (18 points)

Answer 1

Scatter plot is the answer for this type of graph of intelligence.

We can go up by 12 or 24 on the side graph

0,12,24,36,48,60,72,84,96,108 etc. So their will be 20 values if 12 and this best, labeled 12-228 this is because it stops at 202 and 228 may encourage other parents who read to take part in telephone interviews etc.

So that the first number 8 or 10 on y axis shows between 0 +12 (2/3 up to 12 low down) can be read as 2/3 of the first value so under 12 looks good. You will see that Step 1.

Step 2 Label x and y at end axis afterwards

Step 3. Write the name at side of y axis line

Call it Attitudes to college education from the 605 parents interviewed.' = y line.

Step 4. Write the name under x axis line

Call it Percentage of parents who both disagree or agree = x axis

Step 5 We can color code red blue and purple or pink dots to represent cultural race just three colors like orange blue and silver.

Step 6 Group each grid in the chart into percentages

by using imputing the value before /202 the first group ie) 10 (B) strongly disagree you enter into calculator 10/202 = 4.95% percentage and do this a few times for each

11/202 shows somewhat disagree percentage for black parents (B) can be put next to each result. (B) SOMD = 5.44%

Then when you do Hispanic start with 8/202 as this is under 10 we move the decimal back still 2 units if it was a larger number it would still be placed back 2 units to the left (H) STrD = 3.96%

Explanation:

So for step 6 you just need the data ive done 4 for you just 8 more needed for percentages.

Step 7. You design a way to show all the percentages so you condense the data to evenly show a broad graph

We know that 154/202 = 76.23% is the highest percent so if you are showing 8 or more values we can show 10 values 10%, 20%, 30% at the bottom of the x axis.

Just remember to do your percentages 8/201 for white parents as the number 202 was for the other groups.

Step 8. Do a color code last to the right. Just away from any dots with Black parents ------- put the color in the bar

one on top of each other in a box to the right of the graph after the letter x but higher up.

Step 9 You could draw a line of fit and call it a scatter graph

And underneath the actual graph write 2 lines about what a line of fit is.

This shows a modest and intelligent way of keeping groups in proportion to their warranted and valued answer.

This must be a subtle way for parents to absorb all advanced data shown.

Its just a challenge to see if all the percentages can fit and meet up in a coordinated way. If it doesn't work then perhaps you can relabel x axis frequency and show the same data on y on x but a new name so it can always be understood and both meet at same numbers. But i think the percentages would work and show better intelligence, along with a color code showing pretty stars or dots to make the colors coordinated is another way to make all parents feel valued whatever the race.
