## Each Statistics in the Media discussion assignment has two components

``````Find an example of statistical data portrayed in the popular media. This could be a news item, could include a graph or chart, or could be a report on a poll. You cannot repeat a post made by another student. You must post the image, video, or link. (1 point)
Source: You must also include the source(s) of the data. (1 point)
Variable: Identify the variable(s) and whether they are discrete or continuous. (2 points)
The Problem: Based on your knowledge of statistics, research design, and scientific reporting, critically evaluate the claims made and/or the method of graphical representation. (You can refer to your textbook, and/or other scientific sources). Length: 1-2 sentences. (2 points)
``````

``````You will need to thoughtfully comment on at least TWO posts made by other students in the class. You will only be able to comment AFTER you have made your own post.
Each comment is worth 2 points.
DO: These comments must reflect an understanding of statistical concepts you have learned in the course and contribute to the discussion of critically evaluating the data presented in the post. For example, this could include more accurate ways of presenting or interpreting the data. Length: 1-2 sentences per comment.
DON'T: You may NOT include personal or subjective comments directed towards another student or the instructor, or any personal, political or religious views that are disrespectful to others. Evaluate the content, not the source or person presenting the information. Please keep in mind that this is a scientific discussion of data we might encounter in our everyday lives.

## explore the dataset to understand what you are working with

Before diving into your data, it's always best to first explore the dataset to understand what you are working with.

1. Considering that you will be combining your two tables of data together at a later stage, how many rows of data are available for your analysis?

1. How are unknown values represented in the dataset?
2. What is the salary range covered by this dataset?
\$254,000
\$200,000
\$235,500
\$238,500
3. How many unique industries are covered by the dataset?
Hint: disregard the unknown values.

1. Consider the following point from your boss's email:
"Where do data scientists work?"
In its current form, this question is ambiguous as it is unclear whether it is asking about the location where data scientists work or the industry in which they work.
Think about how you could approach this question, how to best answer it, and how it could be phrased in data terms. Select the most correct option below.
2. What are locations and industries with the highest number (count) of data jobs?
3. What are the locations with the highest proportion (%) of data scientists relative to all data jobs?
4. What are the industries with the highest salary total (sum) for data scientists?
5. What are the locations and industries with the highest number (count) of data scientists?
6. What are the locations and industries with the highest salary total (sum) for data scientists?

7 Now you've explored your data and thought about how to define your questions, you can now transform the data to make it ready for analysis.
In the job_salary table, the job title and job category are currently given together in the Job Title (Job Category) column, e.g: Healthcare Data Scientist (data scientist).

For further analysis, you will need to separate the job title and job category into separate columns (as shown in the image below).
To create a dedicated Job Title column in your job_salary table, which of the following combinations of text manipulation functions could you use?
Note: the X in the formulae below represents the unseparated Job Title (Job Category) column..

=RIGHT(X,FIND(")", X))
=RIGHT(X,FIND(")", X)-1)
=LEFT(X,LEN(X)-FIND("(", X))
=LEFT(X,FIND("(", X)-1)
=LEFT(X,FIND("(", X))

1. Now create a dedicated Job Category column on your job_salary table and use text manipulation functions to split job category from the job title.
Once you have done this, using your newly created job category column, answer the following to check that you have done this step correctly:
How many data scientist, data engineer, and data analyst jobs (in that given order) are there?
311, 123, 103
109, 315, 119
313, 119, 109
319, 113, 109
303, 119, 109
2. You will also need to join your two sheets of data together, the job_salary table and the company datasets.
Which method(s) below could you use to join the datasets together? Select all correct answers.
Use your method of choice to join the datasets together.
Hint 1: Consider whether your datasets have an equal number of rows to each other.
Hint 2: We recommend joining the company dataset onto the salary dataset.
Manually copy the data from one table and insert onto the side of the other table
3. Manually copy the data from one table and insert it below the other table
4. Use INDEX/MATCH
5. Transform the data in both sheets into Tables and then use Excel Power Query to append the tables together
6. Transform the data in both sheets into Tables and then use Excel Power Query to merge Queries
7. There's no need to join the datasets together as you'll analyse each table separately
8. Use VLOOKUP
9. Now that you have consolidated your two tables of data together, answer the following question to check that you have correctly joined your data:
What is the average salary of a Data Scientist (using your newly created Job Category column) in the Aerospace & Defense industry? Round your answer to the nearest whole number.
Hint: remember that filters hide rows of data, but don't remove them. Ensure that your calculation only includes filtered cells and not the hidden cells.
\$110,679
\$66,344
\$128,302
\$63,658
\$123,816
\$120,294

## Math Reasoning Graded discussion assignment: Solve normal distribution assignment

Graded Discussion: Solve Normal Distribution Application

For this graded discussion, you will be given a scenario to analyze using a cumulative from the mean z-table.
Requirements:

A minimum of two posts is required.
You must give a detailed solution for each part in your first post to get full credit.
It is not enough to just give the final answer. You must show steps or explain your reasoning.
If it is easier, you can write your solution out on paper, take a picture, and upload it to the discussion as a PDF file. The PDF file type is the only file type that will be accepted.
You will be able to see other students' posts once you post your own solution.
Review their responses to determine if they agree with your own.
If they are different, explain which post you think is correct, yours or theirs.
If your original post was incorrect, reply to yourself with a correction. Don't worry! You will not lose points for an incorrect answer, as long as you make a reasonable effort at the first post and post a reply with the correct answer.
Complete required posts by the posted deadline.

Part 1: Prepare
Familiarize yourself with the following data.
In 1955, scientists R.R. Sokal and P.E. Hunter analyzed the affects of pesticides on houseflies. Among the data sets they collected were samples of housefly wing lengths. These are normally distributed. The data they collected is summarized in the following frequency distribution.

Normally Distributed

## Example of a probability question in Pearson MyStatLab

Probability Question Example
The following question is a probability question for tossing a fair coin presented in Pearson My STATLAB statistics. Note that probability concepts are the building blocks for any introductory statistics course. To solve the problem, one would have to write down the possible outcomes, and associate each outcome with some probabilities.
Two fair coins are tossed​ (say a dime and a​ quarter). The two possible outcomes for a single coin are​ heads, h, and​ tails, t. Give each of the following.
​(a) the sample space
​(b) the probability of heads on the dime
​(c) the probability of heads on the quarter
​(d) the probability of getting both heads
​(e) the probability of getting the same outcome on both coins
