02. Video Tutorials (7)

Resource type Compute z-scores for variables in SPSS
How to use SPSS to compute z-scores for a variable. Choose one of two available methods. This resource from the "SPSS Tutorial Series" is contributed to the statstutor Community project by Christine Pereira, Brunel University and reviewed by Tim Sparks, Coventry University. It was developed with sigma resource development funding.
Resource type Confidence Intervals and Error Bars in SPSS

It was developed with sigma resource development funding.
Resource type Select a random sample of data or range of cases to analyse in SPSS
How to use SPSS to select a random sample of cases to analyse from your data set. This resource from the "SPSS Tutorial Series" is contributed to the statstutor Community project by Christine Pereira, Brunel University and reviewed by Alun Owen, University of Worcester. It was developed with sigma resource development funding.
Resource type Select specific cases to analyse in SPSS
How to use SPSS to select specific cases (i.e. rows of data) to analyse. This can be individual case selections or groups of cases (e.g. select all males/females, etc.). This resource from the "SPSS Tutorial Series" is contributed to the statstutor Community project by Christine Pereira, Brunel University and reviewed by Alun Owen, University of Worcester. It was developed with sigma resource development funding.
Resource type Use 'Split file' to analyse groups separately in SPSS
How to use 'Split file' to analyse groups separately in SPSS. By using the Split file tool, SPSS will analyse groups of a categorical variable separately. E.g. split your file by gender to analyse males and females separately. This will not physically split your file - all your data stays in the same place.

It was developed with sigma resource development funding.

03. Teach Yourself Worksheets (4)

Resource type Calculating the Mean, Median and Mode (Worksheet)
This teach yourself worksheet explains how to calculate the mean, median and mode, which are the most commonly used measures of central tendancy or average for a data set.
Resource type Calculating the POPULATION Variance and Standard Deviation (Workseet)
This teach yourself worksheet explains how to calculate the POPULATION variance and standard deviation. Note: this worksheet uses a divisor of "n" which assumes you have data on every member of the population. If you only have a sample then use the divisor "n-1" instead.
Resource type Estimating the Mean from Grouped Data (Worksheet)
This teach yourself worksheet explains how to estimate the mean from a grouped frequency table. For example, in a survey you may have asked participants to indicate an age range rather than asking their actual age.
Resource type Estimating the POPULATION Variance and Standard Deviation from Grouped Data (Worksheet)
This teach yourself worksheet explains how to estimate the POPULATION variance and standard deviation from grouped frequency data. For example, in a survey you may have asked participants to indicate an age range rather than asking their actual age. Note: this worksheet uses a divisor of "n" which assumes you have data on every member of the population. If you only have a sample then use the divisor "n-1" instead.

04. Tests and Quizzes (1)

Resource type Business Statistics 1 - Numbas
5 questions. 1. Choosing whether given random variables are qualitative or quantitative. 2. Deciding whether or not three sampling methods are simple random sampling, stratified sampling, systematic or judgemental sampling. Also whether or not the method of selection is random, quasi-random or non-random.3. Given a table of the number of days in which sales were between £x thousands and £(x+1) thousands find the relative percentage frequencies of these volume of sales.4. Given random set of data (between 13 and 23 numbers all less than 100), find their stem-and-leaf plot. 5. Given sample data find mean, standard deviation, median, interquartile range.
