DATA ANALYSIS & INTERPRETATION

The present study is intended to investigate about Library Effectiveness

by maintaining Library Automation in the University Libraries of

Chhattisgarh. Using appropriate statistical tables, common reference of F-

ratio was applied to test the significance of differences for verification of

various hypotheses. Scores for all the scales collected from all the samples

were analysed separately. The outcome of statistical analysis is compiled in

tables and figures followed by interpretation.

The major prerequisites for effective data analysis using ANOVA

technique are the normally distributed and homogenous data. For judging

normality of any given data, the best ways prescribed are to calculate the

skew ness and kurtosis of the distribution pertaining to the data.

A distribution is said to be skewed when the mean and median fall at

different points in the distribution, and the balance of the centre of gravity

is shifted to one side or the other – i.e. to the left or the right. Ideally the

skew ness value should therefore be exactly “0” (zero) for mean and

median to fall at the same point. The skew ness of the dependent variable

Library Effectiveness in this case is -0.233 with a standard error of 0.121.

Therefore, the data was found to insignificantly skew.

The term kurtosis refers to the flatness of a frequency distribution

compared with the normal distribution. While according to Garrett (1989)

the standard Kurtosis value of normally distributed data should be exactly

DATA ANALYSIS & INTERPRETATION

0.263, the kurtosis value of dependent variable Library Effectiveness in this

study was found to be -0.003 with a standard error of 0.241. Therefore, it

was inferred that the data being insignificantly Kurt was almost normally

distributed.

Further, using the Levene‟s test for measuring homogeneity of the data,

significant results (p=.000) were obtained which denied the homogeneity

of data. Therefore, following McNemar (1962), as the two assumption were

not absolutely fulfilled, but ANOVA being a robust technique that

overlooks near miss cases, for further analysis of results, the level of

significance as an accept/reject criteria was kept stringent at 0.01 level i.e.

(p<.01).

As mentioned earlier, the study further uses a three-dimensional (3x2x8)

ANOVA technique at SPSS to analyse the data whereby numerical values

were assigned for various independent variables of the study. Three levels

of Library Automations were studied as low, moderate and high

respectively. For the dimension of Readers, the two categories were

Teachers and Students respectively. For the dimension of Universities, the

eight respective codes were: PRSU for Pandit Ravishankar Shukla University,

GGU for Guru Ghasidas University, IGKV for Indira Gandhi Krishi

Vishwavidyalaya, IKSV for Indira Kala Sangeet Vishwavidyalaya, HNLU for

Hidayatullah National Law University, CSVTU for Chhattisgarh Swami

Vivekanand Technical University, PSOU for Pandit Sundarlal Sharma (Open)

University and finally KBTV for Kushabhau Thakre Patrakarita Avam

Jansanchar Vishwavidyalaya. Finally, Library Effectiveness was observed as

the dependent variable.

For the first problem, where it was hypothesised that Libraries with higher

automation level will show more effectiveness than libraries with lower level

of automation, the Table 7.1, 7.2, 7.3 and 7.4 below mention the

descriptive statistics and mean scores for the dependent variable Library

Effectiveness at low, moderate, high and total level of Library Automation

respectively.

DATA ANALYSIS & INTERPRETATION

Table 7.4, reveals the overall mean score of 129.62 making a

favourable indication that Library Automations positively effects the Library

Effectiveness perception of Readers. Further, for the effects of various levels

of Library Automations on Library Effectiveness, the mean scores of 66.89,

130.33 and 191.64 respectively at the low, moderate and higher levels of

Library Automation make it clearly evident that higher the Library

Automation more will be the Library Effectiveness perception of the Readers.

For the second problem, that Teachers will perceive higher library

effectiveness compared to Students, the respective mean scores of

Teachers and Students as 148.36 and 110.87 proved that the Teachers of all

libraries perceived their library as more effective compared to their students.

DATA ANALYSIS & INTERPRETATION

The Table 7.5 entitled as the “Analysis of Variance Summary Table:

Overall Library Effectiveness” exhibits the three way ANOVA results for the

dependent variable „Library Effectiveness‟.

According to Table 7.5 whereby significant main effect value (F =

20.148, p=.000) was found thus there remained no two ways to accept the

first hypothesis that Library Automations strongly affect the Library

Effectiveness.

Further the Figure 7.1 below also reveals that with the increase in level of

Library Automation level from low to higher, Library Effectiveness scores also

increase proportionately.

DATA ANALYSIS & INTERPRETATION

For the second problem, that Teachers will show higher Library

Effectiveness compared to their Students National Companies. The Table

7.5, with significant main effect value (F = 16.52, p=.001) exhibited that

there are significant differences between perceptions of Teachers and

Students for the overall Library Effectiveness perceptions higher Library

Automations in their University Library. Further, the Figure 7.2 also shows such

significant difference among the two types of Readers for their perceptions

over Library Effectiveness. Therefore in view of such results, the second

hypothesis too was accepted.

DATA ANALYSIS & INTERPRETATION

The third main effect, „Libraries‟ i.e. the eight University Libraries of

Chhattisgarh, studies the different levels of Automation in subjected

Libraries and its effect on the perception of the Readers over its

Effectiveness state. According to the Table 7.5, again the significant main

effect value (F = 24.15, p=.0001), indicated that the Libraries in the present

study vary with their levels of Automation and resulting in a varying reader

perception over their Effectiveness status.

Figure 7.3 below exhibits the above stated result that the reader

perception on Library Effectiveness varies across PRSU, GGU, IGKV, IKSV,

DATA ANALYSIS & INTERPRETATION

So far, we have discussed the role of independent variables – Level of

Library Automation, Readers and, Libraries. It would also provide useful and

important information if the joint effects of any two or more factors are

studied. The greatest advantage we get from analysis of variance technique

is that it provides an opportunity to examine the interaction between two or

more variables at a time.

It is possible for a treatment to affect one group differentially than it does to

another. Also it is possible for the effect of one treatment to depend on the

specific circumstances under which it is administered. When the effect of one

treatment depends on a second treatment, an interaction is obtained. Here,

in the three-way analysis of variance, we get three such first-order interactions

between any two factors, and one second-order interaction among all the

three factors.

The three first-order interactions that the present study undertook were the

interactions between (1) Level of Library Automation and Reader (2) Level of

Library Automation and Libraries and (3) Readers and Libraries. According to

Table 7.5, all three first-order order interactions were found to have significant

results. Table 7.5 exhibits these significant results as (F = 19.74, p =.000) for Level

of Library Automation and Reader; (F = 19.21, p =.001) for Level of Library

Automation and Libraries; (F = 27.168, p =.002) for Readers and Libraries. From

DATA ANALYSIS & INTERPRETATION

such results it could be inferred that highly significant relationships exist

between the three independent variables used in the present study.

The figure – 7.4 exhibits the first order interaction between the Library‟s

Automation Level and their Readers. The figure suggests a visible gap in

perceptions of Readers i.e. Teachers and Students. Further, the perception of

Readers for Library Effectiveness Increases more with the movement from Low

to Moderate Level of Automation as compared to the movement from

Moderate to High Level of Automation. It is also worthwhile to mention that

with the change in Level of Library Automation the relative increase in Library

Effectiveness perception of Teachers is relatively higher as compared to that

of their Students.

DATA ANALYSIS & INTERPRETATION

The figure 7.5 below exhibits the next first order interaction of Libraries at

various Levels of Automation. The figure clearly indicates that there is a

variance among the scores of various Libraries at the each Level of

Automation. Pandit Ravishankar Shukla University Library scored highest at

all levels, followed by Guru Ghasidas University, Indira Gandhi Krishi

Vishwavidyalaya, Indira Kala Sangeet Vishwavidyalaya, Hidayatullah

National Law University, Chhattisgarh Swami Vivekanand Technical

University, Pandit Sundarlal Sharma (Open) University and lastly Kushabhau

Thakre Patrakarita Avam Jansanchar Vishwavidyalaya. Notably, the

Effectiveness scores of highest and lowest scoring libraries vary least at low

level of automation followed by high level of Automation and vary most at

the moderate level of Automation.

DATA ANALYSIS & INTERPRETATION

The second-order interaction giving the combined effect of Level of

Library Automation, Readers and, Libraries with the dependent variable Library

Effectiveness was also studied. According to Table 7.5, significant F-value for

this second-order interaction (F = 14.114, p=.000) was obtained for this joint

interaction indicating a significant interaction of all the independent variables

together with the dependent variable „Library Effectiveness‟. For Teachers, as

shown in Figure 7.6, it was revealed that Library Effectiveness perceptions of

Teachers increases with a rise in Automation level in all the University Libraries

covered in the present study. Also, this change in perception of teachers in all

libraries varies most at Moderate level of Automation followed by High level of

Automation and least at the Low level of Automation.

DATA ANALYSIS & INTERPRETATION

Further, for Students, the Figure – 7.7 below indicates that like Teachers,

the Library Effectiveness perceptions of Students also increases with a rise in

Automation level in all the University Libraries. Also, this change in perception in

all libraries varies most at Moderate level of Automation followed by High level

of Automation and least at the Low level of Automation. However, as

compared to that of the Teachers, such variance is less at Low level and

relatively more at High level and highest at the Moderate level of Automation.
