Surveys02:16

Surveys

15.0K
Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Stereotypes, Prejudice, and Discrimination

90.9K
Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...

Correlations02:20

Correlations

33.6K
Correlation means that there is a relationship between two or more variables (such as ice cream consumption and crime), but this relationship does not necessarily imply cause and effect. When two variables are correlated, it simply means that as one variable changes, so does the other. We can measure correlation by calculating a statistic known as a correlation coefficient. A correlation coefficient is a number from -1 to +1 that indicates the strength and direction of the relationship between...

Null and Alternative Hypotheses01:16

Null and Alternative Hypotheses

8.8K
The actual hypothesis testing begins by considering two hypotheses. They are termed  the null hypothesis and the alternative hypothesis. These hypotheses contain opposing viewpoints.
The null hypothesis, denoted by H0 is a statement of no difference between the variables—they are not related. This can often be considered the status quo. As  a result if you cannot accept the null, it requires some action.
The alternative hypothesis, denoted by H1 or Ha, is a claim about the...

Comparing Experimental Results: Student's t-Test

1.7K
The t-test is a statistical method used to compare the sample mean with a population mean or compare two means from two data sets. The test statistic is calculated from the standard deviation, mean, and number of measurements in the data set at a selected confidence interval and then compared to a table of critical values at this confidence level. If the test statistic is smaller than the critical value, the null hypothesis is accepted. In this case, we state that the difference between the...

Statistical Hypothesis Testing01:16

Statistical Hypothesis Testing

2.1K
Hypothesis testing is a critical statistical procedure facilitating informed, evidence-based decisions. It begins with a hypothesis, which is a tentative explanation, or a prediction about a population parameter. This hypothesis can be either a null hypothesis (H0), indicating no effect or difference, or an alternative hypothesis (Ha), suggesting an effect or difference.
Statistical significance measures the probability that an observed result occurred by chance. If this probability, known as...

Area of Science:

  • Social Sciences
  • Computer Science
  • Hate Speech Research

Background:

  • Antisemitism is a growing global concern, with social media platforms emerging as key channels for its dissemination.
  • Identifying and quantifying antisemitic content online presents significant challenges due to the scale of data.

Purpose of the Study:

  • To present and describe an annotated dataset for training tweet classifiers to detect antisemitism.
  • To analyze the scope and nature of antisemitic content on social media.

Main Methods:

  • Expert annotation of social media conversations related to Jews and Israel.
  • Development of a dataset for machine learning-based classification of antisemitic tweets.

Main Results:

  • 11% of conversations about Jews (Jan 2019-Aug 2020) and 13% about Israel (Jan-Aug 2020) were labeled antisemitic.
  • Antisemitic content frequently involves themes of global Jewish conspiracy, the Middle East conflict, and Holocaust denial or distortion.

Conclusions:

  • The annotated dataset provides a valuable resource for developing automated tools to combat online antisemitism.
  • Understanding the specific themes and language used in online antisemitism is crucial for effective detection and mitigation strategies.
