Topic: Independent and Dependent Variables
Professor instruction bellow :
Hi Class! For this discussion you will want to use the topic you presented in Week 2 and keep building on that for your study. This week is intense, please review hypothesis statements if you have not written those types of statements in a while.
Thanks, Prof
************************** Topic I wrote in week 2 *********************************
A smart home is a home whose electrical appliances like TVs, computers, lighting, heating and even surveillance camera systems are equipped such that they can be controlled remotely by a smartphone or a computer (Robles, Tim, & Das, 2010. Smart locks are joining the smart home technology (Wagner, et al, 2016). The research problem on this topic is whether smart homes are secure. The hypothesis for this topic is that smart homes are not secure. The keywords used in this research are; smart homes, smart locks, remote control, computer, smartphones, and security. I chose the topic because it is a significant emerging technology and in my opinion, it is also important for people to know security threats that could be posed by the new technology and possible solutions to the problems. One of the big challenges I will face in this study is the scarcity of information on the web about smart locks as an IoT of smart homes.
Wagner et al, (2016), reveal flaws in implementation, design and interaction models. They point out to August’s auto-lock and unlock as a flaw. The highlight that the sensor has problems that can leave the owner leaving the door unlocked unknowingly. Segal (2018) raises the concern for privacy and intimacy. She points out that hackers can get access to router information and personal data stored in it. She adds that data collected by the smart home companies is sold to other companies for financial gains. Smart homes are not entirely safe. Experts like Jeremiah Grossman, a Chief of Security Strategy at Sentinel One cyber security firm is on record saying he cannot personally trust smart locks with his door until in the future, after improvements have been made.
It is therefore evident that smart homes are not entirely safe, thanks to smart locks. Therefore, people should be very keen on the brands they buy, the security and privacy guarantees.

Discussion of Research Methods, Independent-dependent variables Transcript Below
Week 3 – Kumar Chapt 4,5,6,7
Chapter 4 – Research is intended to draw conclusions about a general subject or population based on data taken from a smaller sample. The larger the sample, the more reliable the conclusions.
A research study means formulating a model based on data or observations, to see if you can predict future outcomes based on different data or new observations. Sometimes the model is quantitative, relying on mathematics. Other times, the model is qualitative, relying on comparisons or evidence and observations showing a relationship.
Sometimes there is difficulty when trying to formulate a question, opinion (or hypothesis) into a researchable problem. Formulating the research is like creating the foundation for a building. You should choose a topic which interests you, and which motivates you, since the research itself will be time-consuming. You must narrow-down the scope of the topic so that you can finish the work within the allotted time. The topic should be specific. If you choose a topic that is too broad, or too vague, you may not be able to finish your work by the end date, and your work will show that you are not finished. When you choose a concept for research, you must be clear about what exactly will be measured so that it will clearly relate to your hypothesis. If you are working with data, you must determine early in your work whether data is actually available to you. If you are working with a population, you must be careful to avoid adverse reactions from the subjects, who may also be reluctant to share information, or who may be upset by being the subject of an examination. You should have some familiarity with the research topic. You must know if sufficient scholarly literature exists that will help support your research.
Follow the steps listed in Chapter 4 of Kumar. Identify the field that interests you Dissect the broad into narrowly-defined s aspects Select the narrow aspect that is most interesting What do you want to find out? What is the research question? Formulate objectives – Use phrases such as “…to find out..”, or “..to determine..” Are your objectives feasible? Do you have the time, the resources to finish? Double-check yourself on the above answers
Look at Kumar examples 1, 2 and 3 in chapter 4. What is the makeup, or characteristics of your study population? What are the characteristics that may separate your study population from the global population of possible respondents? Is your sample population representative of the total population? What are the measurements you want to observe? You must also remove ambiguity from your definitions and from your methods for research.
Chapter 5 – A Variable is a concept that can take on a value that can serve as a measurement. Variable values can be numeric, or that can be discreet (A or B, Hi-Medium-Low). By deciding on the values to be measured, you are operationalizing the concept being examined.
An independent variable can stand alone, does not depend on anything else to get its value (red light or green light). A dependent variable relies on another variable to receive its value (moving or stopped). The researcher creates, or theorizes, a model of reality and tests it by manipulating the independent variable and then measuring the dependent variable to see the effect. Does the model demonstrate whether the dependent variable increases or decreases as the independent variable is increased or decreased by the researcher? (see Hughes Chapter 4).
