This document provides guidance on developing a hypothesis and experiment title. It explains that a hypothesis should make a clear, specific, and testable prediction about the relationship between an independent and dependent variable. The hypothesis and experiment title should use a specific format. For example, "If the (independent variable) is (manipulated), then the (dependent variable) will (change)." An experiment title is written as "The Effect of (Independent Variable) on the (Dependent Variable)." Examples are provided to demonstrate how to write a hypothesis and experiment title for different experimental scenarios.

Developing a Hypothesis and Title for your Experiment
The document discusses how to develop a hypothesis and title for a scientific experiment. It explains that a hypothesis predicts the relationship between an independent variable and dependent variable in an "if...then" statement. Several examples are provided of hypotheses and experiment titles that follow the proper format of stating the effect of an independent variable on a dependent variable. Guidance is given on key terms like "effect" versus "affect" and how to clearly define the independent and dependent variables.
Venture lab tech entrepreneurship market survey
The document summarizes research conducted to validate a proposed virtual library business model. A survey of 60 people found that while most were willing to lend books and pay a subscription fee to borrow, they were not willing to travel long distances to collect books. As a result, the business model was updated to have drop-off points in neighborhoods for book exchange, increasing costs and requiring higher subscription fees for the venture to be viable.
Types of Hypothesis-Advance Research Methodology
This Presentation states the details of Hypothesis for students to get help in advance research methodology. Rearchers may also get help from this work.
Developing hypothesis and research questions
The document discusses hypotheses, providing definitions and discussing the nature, types, and formulation of hypotheses. It defines a hypothesis as a tentative statement about the relationship between two or more variables that can be tested. The main types discussed are the null hypothesis, which represents a theory to be tested, and the alternative hypothesis, which is the opposite of the null hypothesis. It also discusses how hypotheses are formulated differently for qualitative versus quantitative research, with qualitative research often using research questions rather than hypotheses.
Pilot study
A pilot study is a small preliminary study conducted prior to a larger research study to test and refine aspects of the proposed research such as research instruments, sampling methods, recruitment strategies and data analysis techniques. It allows researchers to identify potential problems in their research design or methodology and make necessary revisions before embarking on the full-scale research project. Pilot studies help improve the quality, efficiency and validity of the final research study.
Hypothesis
This document provides an overview of hypotheses for a presentation. It begins with learning outcomes which are to explain the meaning and significance of hypotheses, identify types of hypotheses, and illustrate why hypotheses are needed.
The presentation will cover the scientific method, meaning and types of variables, characteristics of good hypotheses, categories of hypotheses including null and alternative, and how to form and test hypotheses. Hypotheses are defined as educated guesses that relate variables and guide research. They must be testable, falsifiable, and contribute to theory. Hypotheses can be categorized by their formulation as null or alternative, by direction as directional or non-directional, and by their derivation as inductive or deductive.
ES7 - Components of Scientific Investigation.pdf
This document discusses the key components of scientific investigation: observations, formulation of problems, and variables. It explains that scientific investigations typically begin with observations using the five senses. Observations can be qualitative, involving description, or quantitative, involving exact measurements. Formulating problems involves asking questions based on observations of interest. When formulating problems, it is important to identify the independent variable being manipulated, the dependent variable being measured, and keep other variables constant. Several examples are provided to illustrate these concepts.
bgfact_stat.ppt
The document discusses statistical analysis of factorial designs, including 2x2 factorial designs. It covers reviewing interactions through examining simple effects and main effects. It also discusses kinds of factorial designs, including between-groups, within-groups, and mixed designs. Additionally, it provides examples of interpreting interactions and main effects, constructing F-tests, and using LSD to describe interactions by comparing cell means in 2x2 designs.

How many independent variables?
The document discusses independent and dependent variables in statistics. It explains that the independent variable is the cause or influencer in a study, such as amount of study time or amount of sleep, while the dependent variable is the effect or what is being influenced, such as test scores. It provides examples of how to identify the independent and dependent variables in studies and word problems about viral infections, background noise, and more.
Experiment on eye witness testimonies thea, jody, rahc, pennie
The students conducted an experiment on eyewitness testimony, replicating a study by Loftus and Palmer. They showed participants a video of a car accident and gave them a questionnaire with questions about details from the video. One critical question was worded differently between conditions - asking some participants if they saw "any broken glass" and others if they saw "the broken glass". Contrary to expectations, participants asked about "any broken glass" were more likely to say they saw broken glass, even though there was none. The students hypothesized this may have been due to an imbalance between male and female participants in each condition.
Variables and Hypotheses
1) The document defines key terms in research methods including variables, independent variable, dependent variable, extraneous variables, research hypothesis, and null hypothesis.
2) Variables are any characteristics that can take on different values or levels. The independent variable is what the researcher manipulates and is presumed to affect the dependent variable, which is measured.
3) The research hypothesis is the researcher's prediction about the relationship between two or more variables, while the null hypothesis states there is no relationship and gets tested statistically with the goal of being rejected.
How many dependent variables?
The document discusses dependent variables in statistics problems. It explains that the dependent variable is the "effect" side of a cause-and-effect relationship, or the "influenced" side of an influencer-influenced relationship. Several examples are provided to demonstrate how to identify the dependent variable in word problems involving research studies. The dependent variable is the main outcome or variable being measured in response to changes in other variables. Problems can have either a single dependent variable or multiple dependent variables.
Research design
1. The document presents 11 claims and then states that all of them are false. It emphasizes the importance of the scientific method to verify answers rather than accepting claims without evidence.
2. People's beliefs and knowledge can come from many sources like rumors, parents, friends, and experiences that are not always accurate. The scientific method helps minimize errors by standardizing steps that can be replicated.
3. The last part of the document discusses identifying problems, forming testable hypotheses, designing studies, collecting and analyzing data, and reporting findings to help verify answers through the scientific process.

- What is the probability that the number on the top of the cube will be greater than 5?
Favourable outcomes: 6
Probability = 1/6
- What is the probability that the number on the top of the cube will be a multiple
Student Led Conference - Morena
This document contains a student's portfolio from school, including assignments and reflections from various subjects. In language arts, the student helped paint a mural based on the book "Roll of Thunder, Hear My Cry." In math, the student scored 100% on a chapter test covering division. In social studies, the student created a brochure to promote the colony of New Jersey as part of a colonial America study.
Monte Carlo
The document describes using a Monte Carlo simulation to model the process of generating English names over multiple generations. It outlines the key processes in the model, including prepending nicknames, appending place names or occupations, shortening names by dropping syllables, and rejecting identical names. The simulation is run with adjustable parameters and the results are compared statistically to real name data to test how well the model fits, rather than requiring an exact match of individual names. The simulation is found to match some properties like name length distribution but not others like the frequency of names containing "smith". This highlights both the utility and limitations of the Monte Carlo approach for this problem.

Students are encouraged to think of additional questions they are curious to investigate.
Mod 19 learning by observation
Observational learning is an important way that humans and other animals learn new behaviors and skills. Key points:
1) Studies by Bandura and others showed that children imitate behaviors they observe in others, whether prosocial or antisocial behaviors.
2) Mirror neurons in the brain help explain how observational learning works on a neural level.
3) Research also links viewing media violence with increased aggression in children, though parental monitoring can reduce these harmful effects.

GNSS spoofing via SDR (Criptored Talks 2024)
In the realm of cybersecurity, offensive security practices act as a critical shield. By simulating real-world attacks in a controlled environment, these techniques expose vulnerabilities before malicious actors can exploit them. This proactive approach allows manufacturers to identify and fix weaknesses, significantly enhancing system security.
This presentation delves into the development of a system designed to mimic Galileo's Open Service signal using software-defined radio (SDR) technology. We'll begin with a foundational overview of both Global Navigation Satellite Systems (GNSS) and the intricacies of digital signal processing.
The presentation culminates in a live demonstration. We'll showcase the manipulation of Galileo's Open Service pilot signal, simulating an attack on various software and hardware systems. This practical demonstration serves to highlight the potential consequences of unaddressed vulnerabilities, emphasizing the importance of offensive security practices in safeguarding critical infrastructure.

GNSS spoofing via SDR (Criptored Talks 2024)
In the realm of cybersecurity, offensive security practices act as a critical shield. By simulating real-world attacks in a controlled environment, these techniques expose vulnerabilities before malicious actors can exploit them. This proactive approach allows manufacturers to identify and fix weaknesses, significantly enhancing system security.
This presentation delves into the development of a system designed to mimic Galileo's Open Service signal using software-defined radio (SDR) technology. We'll begin with a foundational overview of both Global Navigation Satellite Systems (GNSS) and the intricacies of digital signal processing.
The presentation culminates in a live demonstration. We'll showcase the manipulation of Galileo's Open Service pilot signal, simulating an attack on various software and hardware systems. This practical demonstration serves to highlight the potential consequences of unaddressed vulnerabilities, emphasizing the importance of offensive security practices in safeguarding critical infrastructure.
Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

Mutation Testing for Task-Oriented Chatbots
Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.

- 3. THE FOUNDATION OF THE EXPERIMENT The development of a hypothesis is the first step in designing and conducting an experiment. The hypothesis should be: clear, specific, and testable.
- 4. THE HYPOTHESIS… Is the prediction for the outcome of the experiment. States the relationship between the independent and dependent variable!
- 5. FORMAT If the (independent variable) is (describe change) Then the (dependent variable) will (describe change)
- 6. A SCENARIO Mr. Joralemon tested to see if the amount of TV had an effect on how many times a baby wakes up during the night He had his niece watch 1 hr, 2 hrs, 3 hrs, and 4 hrs of TV
- 7. THE EXPERIMENT IV: TV Time (1 hr, 2 hr, 3 hr, 4 hr) DV: How many times his niece woke up during the night Hypothesis: If the (amount of TV time) is (increased), then the (amount of times the baby wakes up during the night) will (increase)
- 8. THE HYPOTHESIS Hypothesis: If the (amount of TV time) is (increased), then the (amount of times the baby wakes up during the night) will (increase) This hypothesis states the relationship between the amount of TV time (IV) and the # of times the baby wakes up (DV)
- 9. EXPERIMENT TITLE Like your hypothesis, you also use a specific format on the title of your experiment Your title also shows the relationship between the IV and DV
- 10. THE TITLE OF YOUR EXPERIMENT… Is written in the following format: “The Effect of (Independent Variable) on the (Dependent Variable).” Remember, in your experiment, you are looking to see if the IV has an effect on the DV
- 11. A SCENARIO Mr. Joralemon tested to see if the amount of TV had an effect on how many times a baby wakes up during the night He had his niece watch 1 hr, 2 hrs, 3 hrs, and 4 hrs of TV
- 12. THE TITLE The Effect of (the Amount of TV Time) on the (Number of times the Baby Wakes Up During the Night).” Remember, in your experiment, you are looking to see if the IV has an effect on the DV
- 13. EFFECT VS AFFECT Effect is a noun. It refers to the outcome of an experiment. It is ALWAYS used when writing Titles. Affect is a verb. It means “to influence or act upon something.”
- 14. SOME PRACTICE 1. Each group must give each student in the group a specific number of 1-4. 2. I will put a scenario up on the screen. 3. Each group will discuss the scenario with each other and identify your variables. 4. I will then call out a student number and a question for you to answer. That student must write down the answer though the teammates can help. 5. I will call a team at random and check to see if you got it!
- 15. SCENARIO 1 Mayor Bloomberg set up an experiment to see if the amount of sleep affects the reading scores of 4th graders
