Types of Data Used in Statistics, Statistics for management and economics keller

  • Quantitative data:Numerical data that can be measured or counted.
  • Qualitative data:Non-numerical data that describes characteristics or attributes.

Methods for Data Collection and Analysis

  • Surveys:Questionnaires used to gather information from a sample population.
  • Experiments:Controlled studies that test hypotheses and establish cause-and-effect relationships.
  • Observational studies:Collect data without manipulating variables, observing natural occurrences.

2. Descriptive Statistics

Descriptive statistics provides summaries and visualizations of data, enabling an understanding of its distribution and key characteristics.

Measures of Central Tendency

  • Mean:Average value of a dataset.
  • Median:Middle value of a dataset when arranged in ascending order.
  • Mode:Most frequently occurring value in a dataset.

Measures of Dispersion

  • Range:Difference between the largest and smallest values.
  • Standard deviation:Measure of the spread of data around the mean.
  • Variance:Square of the standard deviation.

Graphical Representations

  • Histograms:Bar charts that show the frequency distribution of data.
  • Scatterplots:Graphs that show the relationship between two variables.
  • Box plots:Visualizations that show the median, quartiles, and outliers of a dataset.

3. Inferential Statistics

Inferential statistics allows researchers to make inferences about a population based on a sample, enabling predictions and generalizations.

Hypothesis Testing

Hypothesis testing involves testing a hypothesis about a population parameter using sample data. The hypothesis is either accepted or rejected based on the significance level and the p-value.

Confidence Intervals

Confidence intervals estimate the range of values within which the true population parameter is likely to fall, with a specified level of confidence.
