Importance of Influencing | Instant Homework Solutions

Based on your reading of the “Influencing with Statistics” article and Chapter 1 (textbook),  what is the importance of generalizability and validity to research? Review your local newspaper or one of the larger ones like The Washington Post, The Washington Times, NY Times, etc., and find an article that uses statistics. Identify the article, how they use statistics, and if you have any questions about their methods or results. The two sources will be uploaded to use and cite for the assignment. Word count 275-300.

Error Variance | Instant Homework Solutions

“Error Variance When two measurements of an object are taken it is common for them not to be identical. These differences are caused by some errors which are sometimes unavoidable. Errors tend to make results misleading or inaccurate and may lead to nature being misinterpreted. There are two main sources of errors; random and systematic errors (Brereton). Under these there are other sources of error which include; environmental errors, equipment errors, procedural errors, and human error. Systematic errors are measurements that are usually dissimilar from the true value mostly due to the procedure or instrument used (Hogan) . Random errors are errors that occur due to chance either by slight changes in the instruments, the reading measurement method or the environment. Random errors are usually hard to be controlled or may be costly to control them while collecting measurements. Human error is usually mainly due to the limitations of the human abilities.  Factors that affect these sources of error are the; environment, operator (human), units being used in the test, method or procedure, calibration used, and equipment. These factors are supposed to be controlled if measurements taken are required to be precise and accurate (Brereton). Human error can be divided into estimation and transcriptional errors, estimation error occur when one is reading measurements from the instrument while transcriptional error when data is recorded in the wrong way.  Transcriptional errors occur for example when one is entering data and they miss a figure in the computer data sheet. An example of estimation error is when one person might read width as 2.3mm while another reads 2.2mm.  Equipment or instrumental error refers to the error obtained when an instrument is used inaccurately for instance using a calculator that rounds off figures incorrectly. The equipment can also have the incorrect calibration and units under test and these lead to errors. Environmental errors happen when factors of the environment interfere with measurements causing errors (Hogan) . For instance when you are measuring the weight of an object and there is wind which causes the scale to read inaccurate readings. Lastly procedural errors are recorded when different processes are used to determine the answers of same questions and the different procedures lead to the getting of different answers. For example if two individuals use different rounding and one rounds up while the other rounds down , they are bound to get different answers.

2D and 3D Figures | Instant Homework Solutions

Space Figures Go to: http://www.math.com/school/subject3/lessons/S3U4L1GL.html 1. Click on the polyhedron link. Define polyhedron. 2. What are the polygons or flat surfaces of a polyhedron called? What are the intersections of these polygons or flat surfaces called? 3. Click on Next at the bottom of the page to go to Step 2: In Depth. A prism can be generated by moving a polygon (triangle or rectangle) through space. A cylinder can be formed by moving a circle through space. In both cases, depth is being added to a flat surface. Can cones and spheres be generated in the same way? If not, why not and how can they be generated? 4. What space figure has one circle base? 5. What space figure is formed by moving a circle vertically through space? 6. Read Step 3: Examples. According to the first and last questions, square and hexagonal prisms can be formed by moving a square or hexagon horizontally through space. Thisstatement is true only if the square or hexagon is vertical. If the square or hexagon is horizontal, in what direction must it be moved through space to form a prism? How does the movement through space depend on the location of the original flat surface? Cross Sections Go to: https://www.mathsisfun.com/geometry/cross-sections.html 7. What is the cross section of a cube? 8. What is the cross section of a sphere? 9. What is a vertical cross section of a cone? 10. What is the horizontal cross section of this prism?

Data Analysis in Probability and Statistics | Instant Homework Solutions

STEP A – COLLECTING YOUR DATA FIRST 1. Open up Google sheets OR an Apple Numbers, OR a Microsoft Word document. (I would provide the document but I don’t know what apps everyone uses and is familiar with). 2. Label 3 columns across the top Dice 1, Dice 2, Sum of Faces. 3. Go to this website (Links to an external site.). And perform 36 rolls. Record your data in your sheet.  4. Once you have finished, create a frequency table below your count, that corresponds to the sums 2 through 12.  5. Save or export your file as such firstnamelastname.xlsx  ——————– STEP B – YOUR STATISTICS AND SHARING IT WITH YOUR PEERS 1. Your data that was in your record sheet (frequency table) and put it in L1 and L2 in calculator. 2. Find the descriptive statistics using your calculator. 3. Create a histogram using your calculator. (Adjust the window settings if need be – you all had some algebra so you know what you should be looking for far as looking at the axis and scaling. Don’t ask me to help. This is an application of your algebra knowledge). 4. Create a box and whisker plot using your calculator.  5 Start a thread: INITIAL POST – FAILURE TO DO WILL RESULT IN A ZERO OR IF NOT DONE CORRECTLY WILL RESULT IN A LOSS OF  A LOT OF POINTS.  A. Provide using correct notation, the descriptive statistics in your calculator. Yes -type it up (no pictures). Just provide this in list (top- down form) B. Provide a 3 paragraph summary about:  2 paragraphs –  What does your descriptive statistics say about your data? Make conclusions AND answer the question I gave in the beginning about MAKING PREDICTIONS (If you did not do that assignment, ask your peers what it was).  Be incredibly specific. Please use good grammar and no bullet points.  1 paragraph – Describe your histogram and box and whisker plot that you made from your calculator. What is shape? How do know by looking at your calculator displays? STEP A: LOOKING AT YOUR DATA AGAIN 1. Open up your excel file. Create a relative frequency chart below your frequency chart. (Take your frequency of each respective sum/36) 2. Below the relative frequency list. Find the sum of all the relative frequencies.  STEP B: INTIAL POST – START A THREAD – FAILURE TO DO SO WILL RESULT IN A ZERO OR FAILURE TO FOLLOW ALL DIRECTIONS WILL RESULT IN A LOSS OF POINTS START WITH A PARAGRAPH ANSWERING THE FOLLOWING What is the difference between experimental and theoretical probability?  CONTINUE WITH 2 PARAGRAPHS – Talk about your data in reference to Chapter 4 & 5.  Include information about its connections to 1. Probability  (use the relative frequencies)  What was your experiment? What were classified as your your events/simple events, outcomes, sample space?  P(sum of 2) P(sum of 7) P(sum of 3 or sum of an odd number) P(sum of a number divisible by 2 or a sum of a number divisible 4) Observation of mutually exclusive, non mutually exclusive events, dependent events, independent events.  2.  Probability Distributions  Is yours a valid one?  Find the mean  and standard deviation (using your calculator) of the probability distribution. Discuss what this tells us about your data.  FINISH WITH ONE LAST PARAGRAPH. How does your experimental compare the theoretical? Be incredibly specific.

Algebra Calculations | Instant Homework Solutions

Let f(t) represent the temperature of a turkey baking in an oven as a function of time t in the oven (in minutes). This means time is the independent variable and temperature of the turkey is the dependent variable. The turkey was in the oven for 360 minutes and then removed. Note that when something is baked in an oven, the temperature of the oven stays constant. 1. Describe the rate of change pattern over each interval of the graph listed below. (10 points) a. 0 < t < 345   b. 345 < t < 360   c. t > 360   2. Explain what is happening in each interval of your graph in terms of the turkey and its temperature, using complete sentences.
