Data Analysis Of Cronbach's Alpha N Of Itermination
6. DATA ANALYSIS -
First, the reliability of the questionnaire (both customers and retailers) was checked using IBM SPSS Version 20.

Cronbach's alpha is a measure of internal consistency, i.e, how closely related a set of items are as a group. It is considered to be a measure of scale reliability. If the value of Cronbach’s α is greater than 0.6, one can proceed with further analysis. If the value of α is less than 0.6, the questionnaire needs to be redesigned.

• As the p-value is .000 which is less than alpha(α)(0.05), we accept the alternate hypothesis (H1)

• Accepted- H1: There is a significant relationship between the customer’s choice of telecom operator and the company’s advertisement campaigns.

An alpha level of 0.05 is arbitrary and was set as a standard by scientists. One of the key concepts in hypothesis testing is that of significance level or, the alpha level, which specifies the probability level for the evidence to be an unreasonable estimate. Unreasonable means that the estimate should not have taken its particular value unless some non-chance factor(s) had operated to alter the nature of the sample such that it was no longer representative of the population of interest.

The reliability of the PKLA test in piloting calculated through Cronbach’s Alpha was .71, which is considered acceptable. Out of the initial 35 items each having 1 point, the minimum score was 6 and the maximum score was 28, with the mean and standard deviation of 15.78 and 5.26 respectively. The preliminary investigation showed that contrary to teachers’ claims in the first phase of the study (Table 4), the majority of them had low levels of PKLA; the mean score of the participants was also low (15.78 out of 35). Item analysis was run on all the items, that is, item facility, item discrimination, and choice distribution, were calculated and the non-functioning and mal-functioning items were edited. In addition, two of the items were deleted…

Cronbach’s alpha values were acceptable[40] for three of the four subscales suggesting good internal consistency and reliability.[42,43] Cronbach’s alpha values for Section I were low for the PWF and SOP groups, a common occurrence for short scales with less than ten items.[44] Also, a high alpha value was not expected in this subscale as the items mainly elicit information about speech by describing the characteristics of a person’s speech. Thus a high score need not necessarily mean high impact for the Subscale I.…

First of all, reliability of 7 indicator variables was calculated by SPSS (IBM Version 24). Table 3 presented the Cronbach’s Alpha which represent the reliability of survey results. All of Cronbach’s Alpha values are more than 0.7 which are in the recommended acceptable range (Nunnally and Bernstein, 2010). Values above 0.8 can be considered as very good values (Nunnally and Bernstein, 2010).…

There are two basic types of sales promotions: trade and consumer sales promotions. The schemes, discounts, freebies, commissions and incentives given to the trade (retailers, wholesalers, distributors, C&Fs) to stock more, push more and hence sell more of a product come under trade promotion. These are aimed at enticing the trade to stock up more and hence reduce stock-outs, increase share of shelf space and drive sales through the channels. However, trade schemes get limited by the cost incurred by the company as well as the limitations of the trade in India to stock up free goods. Incentives can be overseas trips and gifts.…

Consistency of the data has to be verified before proceeding to more in depth analysis because all the variables have been calculated on a scale and reliability studies the value of measurement. It provides information about the internal regularity of the variables. The Cronbach Alpha Reliability analysis has been used and the Cronbach Alpha coefficient generated by SPSS gives an evaluation of the consistency. Generally, if a Cronbach Alpha coefficient of fewer than 0.60 is obtained, the internal consistency is assumed to be poor; a value in the range of 0.60 to 0.80 is suitable consistency and values above 0.80 are fine internal consistencies.…
