I propose that 4 year-olds and 7 year-olds will perform differently on a standardized reading test, where 7 year-olds will score higher on the test than 4 year-olds.
Write your hypothesis statements (one per IV) in the space below:
Null hypothesis (Ho): The mean score of the 4-year olds and the mean score of the 7-year olds are the same
Alternative hypothesis (Ha): The 7-years olds have a significantly high mean score than the 4-year olds.
Now think about how you can summarize your expectations for each independent variable (IV) into one...
can the topic be something about sports Statistics project For this project you will be picking a topic and doing a hypothesis test for that topic. There will be five parts for this project. The four steps that I have outlined in the course, null and alternate hypothesis, check requirements, find the test statistic and p-value, and compare p-value and write a conclusion. The last part will include citing and printing your source of information. Part 1: Introduction Tell me...
can you do this project for me like use baseball and batting averages or whatever you feel like using we had to create our own problem Statistics project For this project you will be picking a topic and doing a hypothesis test for that topic. There will be five parts for this project. The four steps that I have outlined in the course, null and alternate hypothesis, check requirements, find the test statistic and p-value, and compare p-value and write...
Quantitative Methods and Analysis Course One of the items that businesses would like to be able to test is whether or not a change they make to their procedures is effective. Remember that when you create a hypothesis and then test it, you have to take into consideration that some variance between what you expect and what you collect as actual data is because of random chance. However, if the difference between what you expect and what you collect is...
SPSS Homework 1 Instructions: Review and One-Way ANOVAs (40 points) Please note that for all problems in this course, the standard cut-off (alpha) for a test of significance will be .05, and you always report the exact power unless SPSS output states p=.000 (you’d report p<.001). Also, remember that we divide the p value in half when reporting one-tailed tests with 1 – 2 groups. Problem Set 2: Pearson’s correlation (7 pts) Research Scenario: Is there a positive relationship between...
Sometimes when you are sick, your forehead feels really warm. You might have fever. How can you find out whether you do? By taking your temperature, of course. But what temperature should the thermometer show if your're healthy? Is this temperature the same for everyone? Several years ago, researchers conducted a study to determine whether the "accepted" value for normal body temperature, 98.6°F, is accurate. They used an oral thermometer to measure the temperatures of a random sample of healthy...
NAME Statistics in Psychological Research Homework 4 Your homework must consist entirely of your own work. You will need to show your work for calculations in order to receive full credit. Showing your calculations will also allow us to award partial credit due to minor calculation errors. PLEASE BE SURE TO TYPE THE MAJOR STEPS FOR FULL CREDIT AND ROUND TO 2 DECIMAL PLACES. 1. State the null and research hypothesis for each research scenario. [3pts, 1pts each] a. A...
Select the BEST answer for each of the questions below (I true, F- false). Cirele the letter that corresponds with the answer you have selected. Each question is worth 2 points. [Total 40 points) Answer uestion E1. Power is the ability to reject the null hypothesis when it should be rejected 2. With curvilinear data, the Pearson r statistic is an appropriate, accurate statistical tool In a research report, the term statistically significant is used to indicate that the null...
The Olympic Summer Games is an international multi-sport event that has been held every four years since 1896. Competitors from countries across the world compete against one another, representing their countries, in one or more sports events such as wrestling, rowing, high jump, running races, etc. Events may be separated by the sex of the competitors (male or female) or may be mixed (i.e. males and females competing with each other in the same event). At the end of each...
