For this assignment, you will observe a young child. Please choose a child between the ages of 2 and 5 years old.

Then, complete the following steps:

1) Before you begin your assignment you must:

• Discuss this assignment with the child’s parent.
• Inform the parent that you are not observing the child from the position of an expert.
• Explain that you are a Lifespan Development student and are merely observing the child for a class assignment.
• Tell the parent that you will not be using the child’s name in the report.

2) Observe the child for at least 1 hour.

• You may not babysit or observe a child in your work setting.
• You must try to stay as detached from the child’s interactions as possible! Kids are naturally curious, so it is fine to let them know what you are doing. But the less attention you give them, the less interest they will have in you. 🙂

3) Record any data related to the following domains:

• Physical development
  • Estimate weight/height
  • Gross motor skills
  • Fine motor skills
  • Other physical characteristics or activities
• Cognitive Development
  • Langauge use
  • Creativity
  • Decision making
  • Judgment
• Social Emotional Development
  • Emotions (positive/negative and how handled)
  • Psychosocial stage (you must include this for full credit in this area)
  • Social interactions
  • Self-Concept
  • Temperament
• Cultural Influences
  • Parenting practices
  • Multiple languages
  • Gender roles

4) Write a narrative report of what you observed of the child. Use complete sentences and paragraphs. In your report:

• Introduction with child’s demographic information (age, gender, family arrangement – if known, and/or identify primary caregivers)
• State that you received permission to complete the observation
• Discuss observations and divide into sections based on
  • Physical domains
  • Cognitive domains
  • Social/emotional domains
  • Cultural influences

Be sure to use formal, clinical, development language in your report. The more specific vocabulary you use, the better!

The paper should be no less than 4 pages and double spaced. You do not need in-text citations for this assignment, as you will be writing about your observation and simply including vocabulary from the book.

Answer Questions #1-8. Do not need to show work.

1.Use the following Probability Model that represents the different amounts of money a player can win from a certain game. Use this Model for all questions on this review.

Outcome $0 $6 $10 $100

Probability 0.62 0.21 ? 0.04

Find the missing probability.

2. Find P($100).

3. Find P(~$0).

4. Find P($50).

5. Use the probability model and answer from problem #1 to find the expected value. Do not use the dollar symbol when entering your answer.

6. Find the expected value for the probability model shown below:

Outcome	– $8	$0	$10	$90
Probability	0.43	0.31	0.21	0.05

Enter your solution as a decimal (do not use the dollar symbol).

7. The probability model below is a little bit different. While you can not find the expected value from this table, you should be able to write two equations that must be true in the probability model. If you are told that the expected value is $0.40, which two equations must be true?

outcome	$4	– $2	$1	$19
probability	x	y	z	0.06

Select one:

4x – 2y + z = -0.74 AND x + y + z = 0.94

4x – 2y + z = 1.14 AND x + y + z = 0.06

4x – 2y + z = 0.74 AND x + y + z = -0.94

4x – 2y + z = -1.14 AND x + y + z = -0.06

8. If you know that the expected value for the following probability model is supposed to be $0.48, find the missing value in the table:

Outcome	– $5	-$2	?	$50
Probability	0.50	0.27	0.19	0.04

(do not use the dollar symbol).

In-class Assignment Four

1. Suppose the scores on a recent exam in your statistics class were as follows: 78, 95, 60, 93, 55, 84, 76, 92, 62, 83, 80, 90, 64, 75, 79, 32, 75, 64, 98, 73, 88, 61, 82, 68, 79, 78, 80, 85.
   1. Create a stemplot for these test scores using each 10a value once on the stem.
   2. Create a stemplot for these test scores using each 10 values twice on the stem.
   3. Compare the stemplots created in parts (a) and (b). Are any features of the data apparent in one of them but not the other one? Explain.
2. Refer to the previous test scores.
   1. Create a histogram for the test scores.
   2. Explain how you decided how many intervals to use for the historgram.
   3. Comment on the shape of the histogram.
3. Refer to the previous test scores.
   1. Find the median for the test scores.
   2. Find the mean for the test scores and compare to the median. Which one is larger, and why?
   3. Find the standard deviation for the test score.
   4. Do you think the standard deviation would be smaller or larger if the test score of 32 were to be removed from the data?
4. Refer to the previous test scores.
   1. Create a five number summary.
   2. Create a boxplot.
   3. The test score of 32 should have been identified as an outlier. Which of the three reasons would you use to explain this outlier? Should the outlier be removed when a description of the test scores presented?

RStudio code

This project will be from chapter 4 to chapter 6 in the R book file. See the link

https://www.cs.upc.edu/~robert/teaching/estadistica/TheRBook.pdf

This project will contain 3 files.

• Report word file
• Data.xls file , you can get any datasets from https://libguides.uakron.edu/statistics
• The code.R file

The written report should contain the following six sections:

(1) Introduction to the project; talk about the data and what are they, what are going to do.

(2) Explanations of the data;

(3) Details of the methods;

(4) Results of the data analysis (tables and graphs) explain the data, is it cont or disc. And calculate the mean, median and some statistical functions that you think you should do.

; (5) Discussions and conclusions depend on your datasets.

(6) References of the data.

Calculate the mean and median.

Do some functions and explain the code, the data in the tables and graphs.

https://libguides.uakron.edu/statistics but it should be at least 3 columns and 50 rows. Or any datasets from the internet but, you have to put the link.

you have to put all the code (see the link of R book). You have to use all the code from chapter 4 to chapter 6 in your datasets.

# the code of chapter 4

/* all the code

# the code of chapter 5

/*all the code

# the code of chapter 6
