Evaluation REC 375—Leadership and Management of Parks and Recreation Services
Evaluation Defined • Evaluation is the systematic process of determining the effectiveness of current practices, procedures, and plans • Evaluation is a process that judges worth
Why Evaluate? • Determine that funds are wisely spent • Conduct services efficiently • Reinforce staff efforts or recommend new directions • Assist policy makers in directing the organization toward more productive channels • Evidence the strengths of services
Types of and Approaches to Evaluation • Outcome Evaluation • Process Evaluation
Outcome Evaluation • Also called product evaluation, program evaluation, impact evaluation or summative evaluation • Documents the effect of a service on a client
Process Evaluation • Also called formative evaluation • Determines whether the service has been conducted in an efficient, legal, and ethical manner • Produces information during and after the delivery of the program or service that judges the worth of its development and operation
Scope of Evaluation • Annual evaluation of goals and objectives • Annual review of policies • Needs assessments • Management information systems • Performance appraisal of personnel • Program effectiveness • Equipment cost-effectiveness • Risk management • Fiscal accountability
Steps in the Evaluation Process • Determine the evaluation issues • Select an evaluation design • Collect the information • Analyze the information • Prepare a report • Implement the findings
Maintaining Research Integrity • Be objective • Minimize bias • Approach the project fairly and honestly • Understand the principles and procedures of evaluation • Have exceptional mastery of the tools of research • Be concerned with honest and careful evaluation
Sampling Techniques • Probability Sampling • Non-probability Sampling
Probability Sampling • Probability sampling methods are based on randomness • Desire is to be able to “generalize” to the entire population from which the sample is drawn • Most common method is simple random sampling—all members of the study population have an equal opportunity to be chosen • Fishbowl Technique • Random sampling with replacement • Random sampling without replacement • Also can use a table of random numbers or computer based selection
Probability Sampling, continued • Not always possible to select respondents with complete randomness • Stratified sampling • Systematic sampling • Deliberate sampling
Stratified Sampling • The overall population of respondents is divided into several different subgroups according to common characteristics—age, gender, ethnic or racial identity, socio-economic status, etc. • 20 basketball teams, 30 soccer teams, 25 volleyball teams, 35 baseball teams • Want a 25% survey sample • Take 25% of each category as the stratified sample
Systematic Sampling • This selection method occurs when some “system” is applied to the subjects • Interview every 5th person that comes by • While systematic selection approximates a random sample, it does not strictly satisfy the definition of random sampling and, hence, is not entirely bias free • It is quick, efficient and saves time and energy
Deliberate/Purposive Sampling • With this method, the researcher knows that specific characteristics exist in a certain segment of a population • Since these traits are extremely critical to the results of the investigation, the researcher deliberately selects those subjects who contain the characteristics • This selection process is always biased
Non-Probability Sampling • Samples not selected at random • Intact classes, volunteers, a typical group or individual • Intact or available groups impose a serious restriction on the researcher’s ability to generalize the data obtained to the larger population from which the sample was drawn
Information Gathering Methods • Questionnaires and structured interviews • Unstructured interviews and focus groups • Observations • Document study/secondary data review • Non-reactive or unobtrusive measures • Physical traces
Analysis of Information • Information gathered or measured is essentially nothing more than numbers or words—”raw” data • Need to analyze the “raw” data to determine exactly what it means
Quantitative Data Analysis • Describing Data • Frequency distributions • Measures of central tendency • Mean, mode and median • Measures of variability • Standard deviation, spread of scores • Measures of relationship • Chi-square test (named variables) and Pearson correlation (numerical variables)
Quantitative Data Analysis • Inferring or inferential statistics • Measure differences between variables • T-test—is there a significant difference between the scores of 2 groups (compares means) • Analysis of variance—is there a significant difference between the scores of 3 or more groups
Quantitative Data Analysis • Always have issues regarding “Reliability” and “Validity”
Reliability • Refers to whether the repetition of a study or measurement will result in the same or a very similar answer • Do I get the same answers again and again? • If subjects stand on a scale and the subjects are the same weight, does the scale record their weight as equal
Validity • Refers to whether the evaluation actually measured what was intended to be measured • Is the weight of the subjects who stood on the scale accurate? Do they really weigh what the scale says?
Qualitative Data Analysis • Not all data that is collected is quantitative • Some of the data is qualitative • Text (narrative), photographic or video form • Look for themes and commonalities
