Study Notes
Incidental Reports and Data Collection
- Incidental reports document mistakes, errors, and accidents to identify trends for corrective action.
- Experiments are conducted in laboratory wards for investigations and fundamental research purposes.
- Surveys assess the incidence or prevalence of health or disease conditions.
- Retrospective collection refers to data gathered after patient discharge.
- Concurrent collection involves data collected during the patient’s hospital stay.
- Manual data entry involves entering information on worksheets/forms for later processing.
Descriptive Statistics
- Descriptive statistics gather, classify, present, and summarize data to describe group characteristics.
- Frequency distribution assesses how often cases appear, calculated by counting occurrences and summing totals.
Statistical Measures
- The median is the middle score in a dataset, determined by arranging values in order.
- The mode refers to the most frequently occurring value within a dataset.
- Weighted values and weighted mean utilize the Likert-point scale for more nuanced averages.
- Percentiles divide a dataset arranged in ascending order into 100 equal parts, indicating rankings.
Quantitative Data Analysis
- Large quantitative data about any variable should be summarized using a frequency distribution table.
