Usage

KitchenhamEtAl.CorrelationsAmongParticipants.Madeyski10

Format

'KitchenhamEtAl.CorrelationsAmongParticipants.Madeyski10': a data frame with 45 rows and 10 variables:

ExperimentID

<fct>| ExperimentID: This experiment is the only cross-over experiment in the family of TDD and Pair-Programming experiments conducted by Madeyski, so all values in this column are set to 'P2007'.

ParticipantID

<fct> | Participant ID: An identifier for each participant, unique for a specific experiment.

SequenceGroup

<fct> | Experimental Sequence Group: A (TLSP-TFSP), B (TFSP-TLSP)

System

<fct> | Software system to develop: Smell (a tool for identifying bad code smells in Java source code through the use of a set of software metrics) or Library (a library application)

Period

<fct> | Time period of the cross-over experiment: 1 or 2

Treatment

<fct> | Experimental Treatment: Test-First Solo Programming (TFSP) vs Test-Last Solo Programming (TLSP)

PATP

<dbl> | Dependent variable: Percentage of Acceptance Tests Passed

NATPPH

<dbl> | Dependent variable: Number of Acceptance Tests Passed Per Hour

CBO

<dbl> | Dependent variable: Mean value of Coupling Between Objects (CBO), see CK set of metrics

WMC

<dbl> | Dependent variable: Mean value of Weighted Number of Methods in Class (WMC), see CK set of metrics

RFC

<dbl> | Dependent variable: Mean value of Response For a Class (RFC), see CK set of metrics

CrossOverID

<fct> | Cross-Over Code. This experiment is a simple two-group cross-over experiment with one cross-over code, so all values in this column are set to 'CO1'. However, four-group experiments require a code to identify the linked sequence groups (although that can be deduced from the system used in the first time period). A crossover code is also essential for non-parametric analysis.
