● 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.

What makes a Cereal Healthy
![Page 3: Which Cereals are the Healthiest? Michaela Todd, Halley White, Kalli Rasmussen, Ellie Hagen.](https://reader036.fdocuments.in/reader036/viewer/2022062407/56649daa5503460f94a98dc1/html5/thumbnails/3.jpg)
● 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 data

Quantitative:● Serving Size● Calories● Fat (grams)● Sodium (grams)● Sugar Content (grams)● Fiber
Qualitative:● Is the cereal healthy?● Kid friendly
Variables of Interest
![Page 5: Which Cereals are the Healthiest? Michaela Todd, Halley White, Kalli Rasmussen, Ellie Hagen.](https://reader036.fdocuments.in/reader036/viewer/2022062407/56649daa5503460f94a98dc1/html5/thumbnails/5.jpg)
● 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 Cereal
![Page 6: Which Cereals are the Healthiest? Michaela Todd, Halley White, Kalli Rasmussen, Ellie Hagen.](https://reader036.fdocuments.in/reader036/viewer/2022062407/56649daa5503460f94a98dc1/html5/thumbnails/6.jpg)
● 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?

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.
![Page 12: Which Cereals are the Healthiest? Michaela Todd, Halley White, Kalli Rasmussen, Ellie Hagen.](https://reader036.fdocuments.in/reader036/viewer/2022062407/56649daa5503460f94a98dc1/html5/thumbnails/12.jpg)
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.
![Page 13: Which Cereals are the Healthiest? Michaela Todd, Halley White, Kalli Rasmussen, Ellie Hagen.](https://reader036.fdocuments.in/reader036/viewer/2022062407/56649daa5503460f94a98dc1/html5/thumbnails/13.jpg)
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.
![Page 14: Which Cereals are the Healthiest? Michaela Todd, Halley White, Kalli Rasmussen, Ellie Hagen.](https://reader036.fdocuments.in/reader036/viewer/2022062407/56649daa5503460f94a98dc1/html5/thumbnails/14.jpg)
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).
![Page 15: Which Cereals are the Healthiest? Michaela Todd, Halley White, Kalli Rasmussen, Ellie Hagen.](https://reader036.fdocuments.in/reader036/viewer/2022062407/56649daa5503460f94a98dc1/html5/thumbnails/15.jpg)
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).
![Page 16: Which Cereals are the Healthiest? Michaela Todd, Halley White, Kalli Rasmussen, Ellie Hagen.](https://reader036.fdocuments.in/reader036/viewer/2022062407/56649daa5503460f94a98dc1/html5/thumbnails/16.jpg)
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).

Serving Size v. Calories
● x-axis: Calories● y-axis: Serving Size (cups).● Correlation: 0.227● Coefficient 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.
