Two potential problems with missing data:
1. Large amount of missing data – number of valid cases decreases – drops the statistical power
2. Nonrandom missing data – either related to respondent characteristics and/or to respondent attitudes – may create a bias
Missing Data
![Page 15: Data analysis process - Seton Hall University, New · PDF fileProcedure: Analyze>Descriptive statistics>Crosstab Statistics: correlation, Chi Square, ...

Missing Data Analysis
Examine missing data
By variable By respondent By analysis
If no problem found, go directly to your analysisIf a problem is found:
Delete the cases with missing dataTry to estimate the value of the missing data
![Page 16: Data analysis process - Seton Hall University, New · PDF fileProcedure: Analyze>Descriptive statistics>Crosstab Statistics: correlation, Chi Square, ...

Use Analyze > Descriptive Statistics > Frequencies
Look at the frequency tables to see how much missing
If the amount is more than 5%, there is too much. Need analyze further.
Amount of missing data by variable

1. Use transform>count2. Create NMISS in the target variable3. Pick a set of variables that have more
missing data4. Click on define values5. Click on system- or user-missing6. Click add7. Click continue and then ok8. Use the frequency table to show you
the results of NMISS

Use Analyze>descriptive statistics>crosstabs
Look to see if there is a correlation between NMISS (row) and another variable (column)
Use column percents to view the % of missing for the value of the variable

Proceed anyway In SPSS Options:◦ Exclude case listwise – include only cases that
have all of the variables◦ Exclude cases pairwise – excludes only if the
variables in the analysis is missing◦ Replace with mean – use at your own risk
What to do about the missing data?

Three steps of factor analysis
1. Assessment of the suitability of the data for factor analysis
2. Factor extraction3. Factor rotation and interpretation
![Page 33: Data analysis process - Seton Hall University, New · PDF fileProcedure: Analyze>Descriptive statistics>Crosstab Statistics: correlation, Chi Square, ...

1. Assessment of the suitability
1. Sample size: 10 to 1 ratio2. Strength of the relationship among
variables (items) – Test of Sphericity3. Linearity4. Outliers among cases
![Page 34: Data analysis process - Seton Hall University, New · PDF fileProcedure: Analyze>Descriptive statistics>Crosstab Statistics: correlation, Chi Square, ...

Step 2. Factor extraction1. Commonly used technique principal
components analysis2. Kaiser’s criterion: only factors with
eigenvalues of 1.0 or more are retained –may give too many factors
3. Scree test: plot of the eigenvalues, retain all the factors above the “elbow”
4. Parallel analysis: compares the size of the eigenvalues with those obtained from randomly generated data set of the same size
