In this exercise you will follow through our textbook, History of Teacup Giraffes, Module: Introduction to the Normal Distribution. Make sure to read the module before you do this exercise.

The code chunk below creates the teacup giraffes dataset simiar to the on in the textbook. You will work with this data set for the quiz.

##   Location    Height
## 1  island1  9.753944
## 2  island1  9.603097
## 3  island1  6.803954
## 4  island1  6.739188
## 5  island1  3.406931
## 6  island1 10.441147

Q1 What is a distribution of data? Describe in your own words.

distribution is the shape of the data set.

Q2 What can you learn from a distribution?

you learn about all the values the variable takes on and when the data is split into groups. how often the values occur and the shape, center an amount of variability in the data.

Q3 Why is it important to know the data’s statistical properties?

it becomes helpful for later when describing certain statistical tests.

Q4 Describe three characteristics of the normal distribution in your own words.

There is a single eak, mass of the distribution is centered, there is symmetry about the center line.

Q5 Create a histogram.

Q6 Add different colors for each group in the histogram.

Q7 Explain why the sample size is important in your learning about the population of teacup giraffes in the islands.

Hint: Read “Things to think about” at the bottom of the webpage.

the sample is a subset of the population so it helps you try to learn more about the amount of giraffes.

Q8 Hide the messages and the code, but display results of the code from the webpage.

Hint: Use message, echo and results in the chunk options. Refer to the RMarkdown Reference Guide.

Q9 Display the title and your name correctly at the top of the webpage.

Q10 Use the correct slug.
