Content
In units three and four you studied data analysis tools. You are to revisit that material and apply the acquired skills and concepts where appropriate. Since the culminating project must involve the organization and analysis of a large amount of data, the skills of these units must be part of all culminating projects.
- Is the data you have collected pertinent to your project?
- How valid is the data?
- What sampling techniques were used to collect the data?
- Is there possible sampling bias and/or variability?
- Have you organized the data in a way that facilitates its manipulation and retrieval?
- Have you computed the measures of one-variable statistics (mean, median, mode, range, interquartile range, variance, standard deviation) where appropriate?
- Have you chosen a regression that models the relation between two variables?
- Have you described the relationship between two variables by interpreting the correlation coefficient?
- Can the normal distribution be applied with the data in your project?
- Have you included z-scores and percentiles where appropriate?
