IntroductionWe chose this data because everyone that

texts while they are driving is a danger to others on the road, not just themselves.

It is an important topic because accidents that are cause d by drivers texting can be harmful to others that choose to not text while driving.

Raw DataWe distributed 550 surveys310 surveys were returned to usOnly 153 of those surveys could be used

because 157 upperclassman do not have their license.

proportion.Margin of Error - .064Confidence Interval - .577<p<.705S.S. – We can be 90% confident that between

57.7% and 70.5% of 11th and 12th grade students have texted while driving.

Comparison of Confidence IntervalsObviously, as the Confidence level increases

the Confidence interval will have a wider percentage range.

With a larger Confidence level, the margin of error will increase causing a change in the Confidence interval.

Although we had different values for each confidence interval, the values represented the same data.

Why we use Confidence IntervalsWe use confidence intervals so that we can

get a representative range of values instead of just a single value.

Confidence intervals visually show the amount of people that responded to the survey.

Pros and Cons of our SurveyPros Cons

Completely random sample.

A lot of data was returned to us.

Survey was distributed to all upperclassman homerooms, so everyone had the opportunity to answer.

More than half of the people did not have their license.

During the survey not all upper classman were available to participate.

People may have lied on their survey.

Summary of FindingsWe found that 63.95% of all upperclassman

students who have their license have texted while driving.

63.55% of upperclassman males responded that they have texted while driving.

64.75% of upperclassman females responded that they have texted while driving.

Therefore we found that the percentage of males and females who have texted while driving is almost equal.

Real World ImpactTexting while driving is a serious problem

and is extremely dangerous to all drivers.
