    • Descriptive statistics calculates measures like mean, median, and standard deviation
    • What is the purpose of data analysis in psychological research?
      Identify patterns and test hypotheses
    • Descriptive statistics uses measures like mean, median, and standard deviation
    • What statistical methods are used in data analysis to identify patterns, trends, and correlations?
      Statistical methods
    • A researcher comparing memory test scores after 8 hours versus 4 hours of sleep is using data analysis.
    • Data analysis uses statistical methods to identify patterns, trends, and correlations
    • What factors influence the choice of data analysis technique?
      Research design and data type
    • A t-test is used to compare the means of two groups
    • What is the purpose of descriptive statistics?
      Summarise data without inferences
    • Match the descriptive statistic with its definition:
      Mean ↔️ Average of all values
      Median ↔️ Middle value in a sorted dataset
    • Standard deviation measures the spread of data around the mean.
    • What is the mean of the following test scores: 60, 75, 80, 85, 90?
      78
    • The median is the middle value when data is ordered.
    • Inferential statistics are used to make inferences about a population
    • What assumptions must be met to use a t-test or ANOVA?
      Data normally distributed, equal variances
    • Statistical significance in inferential statistics indicates that observed differences are likely due to chance.
      False
    • Steps in the data analysis process in psychological research
      1️⃣ Data Cleaning
      2️⃣ Descriptive Statistics
      3️⃣ Inferential Statistics
      4️⃣ Interpretation
    • What is the primary purpose of data analysis in psychological research?
      To extract meaningful insights
    • The first step in data analysis is cleaning
    • Descriptive statistics include measures like mean, median, and standard deviation.
    • Match the descriptive statistic with its purpose:
      Mean ↔️ Indicates central tendency
      Median ↔️ Provides central value, less affected by outliers
      Mode ↔️ Indicates most common value
      Standard Deviation ↔️ Measures data dispersion
    • Inferential statistics are used to make inferences about a population
    • What statistical test is used to compare the means of two groups?
      t-test
    • Data analysis in psychological research aims to identify patterns, trends, and correlations within the data.
    • The choice of data analysis technique depends on the research design
    • What statistical test is used to compare the means of three or more groups?
      ANOVA
    • Descriptive statistics summarize data without drawing inferences about a larger population.
    • The formula for calculating the mean is \bar{x} = \frac{\sum x}{n}
    • What does the standard deviation measure in descriptive statistics?
      Spread of data
    • Inferential statistics require assumptions such as normally distributed data and equal variances.
    • What assumption is necessary for using a t-test to compare two groups?
      Equal variances
    • Statistical significance is determined using p-values
    • What does Cohen's d measure in effect size?
      Standardized mean difference
    • A Cohen's d of 0.8 indicates a large effect size.
    • Match the presentation method with its advantage:
      Written Reports ↔️ Detailed, structured
      Oral Presentations ↔️ Interactive, allows for clarification
      Posters ↔️ Visually appealing, concise summary
      Infographics ↔️ Simple, easy to understand
    • Steps in interpreting research findings
      1️⃣ Review statistical results
      2️⃣ Relate findings to research question
      3️⃣ Discuss limitations and biases
      4️⃣ Draw conclusions and implications
