This study analyzed how the potency perceptions of teams and managers are differentially
impacted by the current stage of team development. Forty-five teams and 45 managers provided
usable data. Descriptive statistics including means, standard deviations, and sample size, are
presented in Table 4 (see Appendix A). Standard deviations for team perceptions of potency are
low and range from 0.12 to 0.22, indicating a high level of agreement. An alpha level of 0.05
was used for all analyses. A z-score examination revealed no univariate outliers.
Normality was assessed by examining skewness and kurtosis. Values revealed no
statistical departure from normality (< 3.29). As an additional check of normality, an inspection
of SPSS Histograms (Figures 2 through 4, see Appendix B) showed the data to be relatively
normally distributed with the exception of manager data on team potency levels being slightly,
negatively skewed. Because no statistical skewness or kurtosis was found, a transformation of
the data was not attempted (Tabachnick & Fidell, 2001).
Levene's test of equality of error variance showed p > 0.05. Therefore, because the p-
value is greater than the alpha level used in the analysis, the assumption of homogeneity of
variance was met.
The following results will address the findings for each hypothesis ordered by type of
analysis. Results of the correlation analyses for H1, H3, and H5 will be discussed first followed
by a discussion of the analyses of variance for H2 and H4.
To measure the strength of association between potency and stage of team development,
a Pearson product-moment correlation analysis was performed to test H1, H3, and H5.
