Question

notice and wonder: battery life. the dot plot, histogram, and box plot summarize the hours of battery life for 26 cell phones that are constantly streaming video. what do you notice? what do you wonder? dot plot. 1 2 3 4 5 6 7 8 battery life in hours. histogram. 0 1 2 3 4 5 6 7 8 battery life in hours. box plot. 1 2 3 4 5 6 7 8 battery life in hours. 12 algebra 1

Explanation:

Step1: Analyze the dot - plot

The dot - plot shows individual data points. We can notice that most of the data points are clustered between 3 and 6 hours of battery life. There are no data points for 1, 7, and 8 hours of battery life.

Step2: Analyze the histogram

The histogram shows the frequency distribution. The highest frequency is in the 5 - 6 hours interval, followed by the 3 - 4 and 4 - 5 hours intervals. The 2 - 3 hours interval has a relatively low frequency.

Step3: Analyze the box - plot

The box - plot gives information about the quartiles. The median seems to be around 4.5 - 5 hours. The inter - quartile range (IQR) can be estimated from the box length. The whiskers show the range of the data excluding outliers.

Step4: Things we might wonder

We might wonder what the average battery life is. We could also wonder if there are any outliers in the data set. Another question could be how these results compare to the manufacturer - claimed battery life for these cell phones.

Answer:

Notices: Most data points are between 3 - 6 hours in dot - plot; highest frequency in 5 - 6 hours in histogram; median around 4.5 - 5 hours in box - plot.
Wonders: What is the average battery life? Are there outliers? How do these results compare to manufacturer - claimed battery life?
