Which Cereals are the Healthiest?
Michaela Todd, Halley White, Kalli Rasmussen, Ellie HagenSlide2
Fiber (more than 3 grams)
Sodium (less than 240 grams)
Sugar (less than 7 grams)*If a cereal meets two of these factors, it is considered moderately healthy.*-For this study, moderately healthy will be considered healthy.http://www.eatingwell.com/nutrition_health
What makes a Cereal HealthySlide3
We used
www.ranker.com
to pick 30 of the most popular cereals. This is a good representation of the cereal population because any brand or type of cereal can be voted for on this website.We got our nutrition facts from caloriecount.about.com Our dataSlide4

Variables of InterestSlide5
Brightly colored box- attracts kids’ attention.
Animals or characters (ex. Froot Loop’s toucan)- Most kids like animated characters so they like to eat cereals with their favorite characters on them.
Games on the back of the box- gives kids something to do while they eat their cereal in the morning.*At least two of the criteria has to be met for the cereal to be considered “kid friendly”.Criteria of Kid Friendly CerealSlide6
Out of our 30 cereal sample, we determined that 21 were targeted towards kids.
Out of the 21 kid targeted cereals, only 6 were considered moderately healthy or healthy.
All 9 cereals that we determined were not marketed towards kids were considered moderately healthy or healthy. According to our data, 6/21 or 29% of kid marketed cereals are healthy while 9/9 or 100% of non-kid marketed cereals are healthy.Based on the results of our study, we can conclude that cereals that are targeted towards children are generally less healthy than cereals that are not targeted towards children. *In this study moderately healthy and healthy are considered healthy.
Are Cereals targeted for young kids more or less healthy than ones not marketed as heavy for young kids?Slide7

Serving Size
Shape- We can see from the histogram and the scatterplot that our data is skewed right.
Outliers- 1.75 cups (Honey Bunches of oats)
Center- Slide 10 shows the measures of center for Serving Size. We can see from the data that our values are concentrated in the .75 -1 cup range but measures of center, like the mean, are skewed right.
Spread- By looking at the Graphs we can see that the data is heavily concentrated between 0 and 1 cups.
From this data we can see that most cereals lie between the 0-1 cup range for Serving Size.Slide12
Calories
Shape- This data is skewed right.
Outliers- 190 Calories (Raisin Bran, Frosted mini Wheats)
150 Calories (Life)
Center- The measures of center on slide 10 also show that the data is skewed right.
Spread- The data is concentrated on the left side of the graph.
We can see from this data that most cereals lie in the 0-122.5 calorie range.Slide13
Fat Grams
Shape- The data is skewed to the right.
Outliers- 3 grams (Reese’s Puffs)
Center- The mean is skewed right as well.
Spread- The data is concentrated on the left side of the graph.
By looking at these graphs, we can determine that most cereals lie between 0-1.5 grams of fat.Slide14
Sodium
Shape- This data is skewed left.
Outliers- 0 grams (Frosted Mini Wheats)
Center- The measures of center show that the data is skewed left.
Spread- The data is concentrated on the right side of this graph.
By looking at these graphs we can determine that most cereals have between 75-225 grams of sodium. Most of our cereals meet the healthy criterion for Sodium more than 75% (Q3= 200).Slide15
Sugar Content
Shape- This data is bimodal.
Outliers- 3 grams (Corn Flakes, Chex, Kix)
Center- The measures of center seem to be accurate. They may be skewed a little bit to the left because of the outlier.
Spread- There is a higher concentration of data on the right side of the graph.
By looking at these graphs we can determine that most cereals fit within the middle values for Sugar Content (6-15 grams). A little more than 25% of our cereals meet the healthy criterion for Sugar Content (Q1= 6g).Slide16
Fiber
Shape- The data is skewed right.
Outliers- 7 grams (Raisin Bran)Center- The measures of center are skewed right as well because of the outlier.
Spread- The data is concentrated on the right side.
From this data we can see that most cereals lie in the 0-3.5 gram range for fiber. This shows us that the majority of our sample does not meet the 3 gram or higher criterion that needs to be met for a cereal to be considered healthy. More than 50% of our cereals do not meet this requirement. (Median= 2g).Slide17
Serving Size v. Calories
x-axis: Calories
y-axis: Serving Size (cups).Correlation: 0.227Coefficient of determination: 0.052 5.2% of data variation can be explained by the LSRL.
LSRL: y=0.003x+0.64 The LSRL does not make sense for this set of data because the relationship is not linear and has an extremely weak correlation.
The residual graph also shows that the LSRL is not reliable because all of the data falls in one section which is a pattern.
