Things to Consider Before You Select Your Methods

• What data collection method(s) would bestcollect the type of data you need from yourtarget population

• What data collection method(s) would helpyou to best answer your researchquestion(s)?

 Think of your available resources: time,staffing, skills, funding, computer technology

• Prior experience

• Potential benefits

• Potential challenges

How to Understandthe Data You Collect

(Data Analysis)

8/14/2019 Community-Based Evaluation Methods

http://slidepdf.com/reader/full/community-based-evaluation-methods 42/56

Why It’s a Good Idea to PlanAhead for Data Analyses

 To determine if the data you collectare practical for analyses

 To review the appropriateness of yourchosen data collection method(s)

 To inform the data collection

instrument you develop  To decide if you will need help with

analyses

8/14/2019 Community-Based Evaluation Methods

http://slidepdf.com/reader/full/community-based-evaluation-methods 43/56

1: Check the Data

Make sure it’s all there

Make sure it makes sense

Catch any mistakes that happened whilefilling out the survey or entering the data

Perform data quality checks throughout yourdata collection process

Common mistakes:– A missing or incomplete response

– An impossible response

– A response unrelated to the question

– A response that contradicts an earlier response

8/14/2019 Community-Based Evaluation Methods

http://slidepdf.com/reader/full/community-based-evaluation-methods 44/56

2: Go Back to theResearch Questions

Be sure to analyze only the data that willhelp you answer your research question(s)

Don’t get side-tracked into analyzing otherpieces of data with your limited time andresources

It is normal to collect more data than you willneed for your evaluation

 You can return to any other interesting dataafter completing your evaluation

3: Reduce the Amount of Data

Save your data in its original form sothat you can return to it if you need to

Look at it in small chunks at a time Eliminate any irrelevant data from

your analysis

Create summary documents to help

you “eyeball” the data more easily tolook for patterns or themes:

– Numeric spreadsheet

– Qualitative summary document

4: Analyze the DataQuantitative Data Analysis: Looking

for Patterns in the Data Calculate averages

– Used with “continuous” data: infinite numberof values

– Add numbered responses– Divide by number of responses

– 2 + 4 + 6 + 10 = 22 22/4 = 5.5

Count frequencies

– Used with “discrete” data: set number of response categories

– Count number of responses

– Number “yes”, number “no”

– Number of choice “A”, Number of choice “B”,

4: Analyze the DataQuantitative Data Analysis: Looking

for Patterns in the Data Calculate proportions

– Is standardized– Equation: % = # of responses/ total # of 

respondents X 100– Example: 45 females/ 100 respondents X 100= 45% of the respondents were female

Calculate rates– Similar to proportions; also standardized

– Easier to compare– Equation: Rate = freq of event in pop/ total pop

X 100,000– Example: 15 cases of lung cancer/ population of 

3,500 X 100,000 = 428 persons per 100,000have lung cancer

4: Analyze the DataQuantitative Data Analysis: Looking

for Patterns in the Data Compare averages, frequencies, proportions,

rates

Compare data from different populations:

– County vs. County– County vs. State

– State vs. US

Compare data from different segments of a

population:– Male vs. female

– African American, white, Latino, Asian, AmericanIndian, etc.

– Children, teens, adults, seniors

– Clientele of your program vs. those who are not

4: Analyze the DataQuantitative Data Analysis: Looking

for Patterns in the Data

Present the data in different ways to seeadditional patterns and relationships:– Chart/ table – shows averages, counts, proportions,

or rates side-by-side– Pie graph – demonstrates percentages of the whole– Bar graph – compares quantities– Line graph – shows trends over time

Determine your findings– Interesting results?

– Interesting patterns or relationships?

–  These are your findings

Step 4: Analyze the DataQualitative Data Analysis: Looking

for Themes in the Data Qualitative data analysis can be deceptively

trickier– Qualitative data is by nature “bigger”

– Analysis requires more analytical thinking andinterpretation

Qualitative data is more open to “bias”– Numbers don’t lie– Analysts bring their values, assumptions and

opinions– Analysts may think they “know” how people feel

Include at least 2, preferably 3 people ineach stage of data analysis to avoid bias

Create as structured of a rocess as ossible

Step 4: Analyze the DataQualitative Data Analysis: Looking

for Themes in the Data1. Read through all of the data at least twice

– Stay “close” or “grounded” in the data

2. Create categories– Focus group or interview questions

– Or specific assessment health issues

3. List themes that emerge from discussion– Sub-categories

– Ideas

4. Rank order according to frequency of appearance

5. Summarize discussion around each theme

6. Determine our findin s

5: Verify Findings

 You now have:

– Some patterns and relationships you found in yourquantitative data

– Some themes and categories you found in yourqualitative data

Based on the results you tallied and summarized,pull out the main findings of each method youused

Verify these findings by re-tallying and re-summarizing the data to make sure you get thesame results

 You can also verify your findings by comparing

the results reached by 2 analysts independently

6: Interpret Findings andDraw Conclusions

Determine what interpretations can be drawn fromeach finding

Invite different perspectives from different Partners and

community members, as this will make yourconclusions stronger

Are the results similar to what you expected? If not,discuss why you think they are different

Brainstorm alternative explanations for your results tomake sure you have considered all possibilities

Make sure the conclusions answer the originalassessment questions

Draw conclusions and recommendations that can be

shared with external audiences
