Solution 1:
The steps for conducting quantitative research are:
- Develop the research methodology: A basic methodology is essential in determining the method for that can vary as per the need
- Developing the sampling frame: The sampling frame helps in determining what exact number of people are needed to complete the research
- Determine the resources needed i.e. people, equipment, etc.: All the resources need to be listed and considered along with costs
- Developing the Timeline: A timeline helps in understanding the position at which project currently is
- Developing the budget: Budget development ensures that total cost remains within bounds
- Conducting a pre-test before fielding the survey and revision of questionnaire if needed: A pre-test helps in error rectification and improvement of data collection process
- Programming the computer for data entry: A computer program ensures that data entered is in order and can be easily processed.
Solution 2:
A stratified sampling technique is preferred because it offers greater precision for the same sample size taken. This leads to a reduction of costs significantly over the other techniques and makes the technique advantageous over the other techniques.
As the error is +/-5% and the confidence level is 95%
The number of the Ford users in the US in 2014 was about 15%
Sample size, n = 196.
Solution 3:
The factors involved in managing workers in the call-center:
- Selection of field workers: Selection should be appropriate as per the needs of customer group
- Training of field workers: Selected candidates undergo training for easily handling the operations
- Supervise the field workers: The workers need to be supervised on the spot in case mistakes happen for more effective working
- Validate fieldwork: The performance of each worker gets validated against a pre-set standard
- Evaluate field workers: The workers evaluation for improvement, feedback as well as appreciation in the form of monetary and non-monetary benefit.
Solution 4:
- ANOVA: It is used in hypothesis testing about mean of a dependent variable that is measured across different groups. It produces an F-statistic which generates a p-value. Validity is ensured when p > 0.05.
- Stepwise regression analysis: It is used where a selection is to be made from a great number of predictor variables. The program calculates an F-to-enter value for non –existent variable and F-to-remove for the existing variables & removes them to achieve the result.
- Stepwise Discriminant Analysis: It is used in determination of discriminatory variable in two or more than two groups that are naturally occurring. Wilks Lambda is used as a test statistic and values like between -.1 to .1.
- Correlation Analysis: It is used to show whether the two pairs are strongly or weakly related. Again, values lie between -1 to 1. R-statistic are calculated for this purpose; and +1 signifies high correlation and -1 signifies low correlation
- Factor Analysis: It is a tool employed in investigation of relationships between variables which are complex concepts like status of socio-economic type, usage patterns etc. The basic statistic used is the correlation coefficient and r > 0.3 for a strong relationship
- Cluster Analysis: This statistical technique employs identification of units which are grouped due to characteristics commonly shared. It uses the same statistic as a factor and discriminant analysis for data clustering.
- MDS: The primary goal is detection of underlying dimensions allowing the researchers for explanation of similarities or dissimilarities which are observed in the objects under investigation. An r-square statistic is used for computation and value above 0.6 is acceptable.
- Co-joint Analysis: It is a statistical technique applied in determination of attribution of values by people. Maximum likelihood estimation statistic is used in the range of -0.1 to 0.1.
- MaxDiff Analysis: This approach is in general used in obtaining importance scores or the preference scores across multiple items. Here, analysis using best and worst cases using paired combinations is used
- Sem/Path Analysis: It is a multivariate statistical analysis technique analyzing relations of structural nature between latent constructs and measured variables. It is a confirmatory technique and focuses on linear constructs and covariance among variables. Here numerical variables indicate the strength.
