1. ### Numeric Weighting

Evaluation Option

Numeric Weighting involves developing numeric scales in order to rate performance against each evaluation criterion and then adding them up for a total score.

2. ### Vote Counting

Evaluation Option

Vote counting is a simple but limited method for synthesizing evidence from multiple evaluations, which involves simply  comparing the number of positive studies (studies showing benefit) with the number of negative studies (studies showing harm). It does not take into account the quality of the studies, the size of the samples, or the size of the effect.

3. ### Realist Synthesis

Evaluation Option

A Realist Synthesis is the synthesis of a wide range of evidence that seeks to identify underlying causal mechanisms and explore how they work under what conditions, answering the question "What works for whom under what circumstances?" rather than "What works?"

4. ### Frequency Tables

Evaluation Option

One of the first steps in analysing data is to construct a frequency distribution table. A frequency table provides collected data values arranged in ascending order of magnitude, along with their corresponding frequencies.

5. ### Crosstabulations

Synonyms:
Cross tabulations
Evaluation Option

Crosstabulation (or crosstab) is a basic part of survey research in which researchers can get an indication of the frequency of two variables (e.g. gender or income, and frequency of school attendance) occurring at the same time.

6. ### Multivariate Descriptive

Evaluation Option

Descriptive statistics provide simple summaries of (large amounts of) information (or data). These summaries are quantitative (e.g. means, correlations) or displayed visually (in graphs, scatterplots, etc.).

7. ### Parametric Inferential

Evaluation Option

Inferential statistics suggest statements about a population based on a sample from that population. Parametric inferential tests are carried out on data that follow certain parameters: the data will be normal (i.e. the distribution parallels the bell curve); numbers can be added, subtracted, multiplied and divided; variances are equal when comparing two or more groups; and the sample should be large and randomly selected.

8. ### Block Histogram

Synonyms:
Histogram
Evaluation Option

A histogram is a graphical way of presenting a frequency distribution of quantitative data organised into a number equally spaced intervals or bins (e.g. 1-10, 11-20…). The interval range is selected to reduce the amount of information while still providing enough variability to picture the shape of the distribution.

9. ### Judgemental Matching

Synonyms:
Judgemental Matching of Comparison Groups
Evaluation Option

Judgemental Matching involves creating a comparison group by finding a match for each person or site in the treatment group based on researcher judgements about what variables are important.

10. ### Realist Analysis of Testable Hypotheses

Evaluation Option

Realist analysis of testable hypotheses tests the program theory by developing a nuanced understanding of ‘What works for whom in what circumstances and in what respects, and how?’.
