A wide range of research methods are used in psychology. These methods vary by the sources of information that are drawn on, how that information is sampled, and the types of instruments that are used in data collection. Methods also vary by whether they collect qualitative data, quantitative data or both. Qualitative psychological research is where the research findings are not arrived at by statistical or other quantitative procedures. Quantitative psychological research is where the research findings result from mathematical modeling and statistical estimation or statistical inference.
5.4 Further replication- repeating the essence of a research study, usually with different participants in different situations, to see whether the basic finding extends to other participants and circumstances. C. Methods of Psychological research 1. Naturalistic Observation- observing and recording behavior in naturally occurring situations without
Quantitative research allows assessing and analyzing data. The association between an independent and dependent variable is studied in detail. Quantitative research can be used to test hypotheses in trials since it is effective in measuring data gathered from the statistics. The main disadvantage of quantitative research is that a large sample of the population must be studied; the larger the sample of people researched, the more statistically accurate the results will be. However,

This means that structured interviews will appeal to positivists as they like sociological methods which gain reliability, gain quantitative date and can cope with a large sample size. Positivists like these because they all help to find the cause of something rather than the effect; this in turn lets positivists to seek the social science aspect of sociology. A sociologist may decide to use structured interviews if they are willing to study a sample of a large number of participants. Structured interviews will also gain a high response rate unlike questionnaires; this is because the interview is face to face rather than putting a set of questions through a door. However participants who are interviewed are those with a lot of time on their hands this can make the sample unrepresentative of the whole population as they may be lonely people who have a lot of time on their hands.
Gilbert takes a psychological view on this and breaks down the ways we make errors in judgment. He says we typically assume that the odds of something are greater because they are easier to remember. Things that are memorable and easy to retrieve that stand out are things that aren’t common at all. We see news stories that follow subject matter that make headlines because they aren’t an everyday occurrence. This can be compared to playing the lotto in that we only hear about the winners so we do not calculate the millions of losers when we decide to play.
There was only a simple law, and that was to not read books as well as think, making “the mind drink less and less.” This doesn’t seem much of a sacrifice because society was filled with far more excitement than literature could offer. Meanwhile, new technology helped people do everyday chores and made life simpler, leaving more time for fun. Like Beatty said, “Life is immediate, the job counts, and pleasure lies all about after work.” Entertainment ruled their society. The parlor walls seem like a god compared to our TVs. The seashell radios are convenience at its best.
Discussion: Analyze and discuss your results. Did your results support your hypothesis? What there a significant difference between the experimental and control subjects? Can any conclusions be drawn? How much confidence do you place in your results?
The question that should be asked is what method should be chosen so that it will be the most cost and time effective? Small Groups VS Individual Expert as Problem Solving Small groups tend to surpass individual experts when alternative solutions are present. Due to the fact that small groups consist of multiple bodies, they can input there own specific experiences and unique knowledge into the task at hand thus coming up with an, if not better, answer than that of the individual. Group work causes less strain to the mind and well as it is a lot less time consuming. Typically higher quality work is present with multitudes of solutions.
However, Boyer Moore algorithm fails to achieve the desired performance for shorter patterns. On the other hand although the KMP algorithm works well for shorter patterns, it is far more complex than the proposed algorithm. The proposed algorithm is easy to understand and implement. III. PROPOSED
