Sanders (1972) and others have shown empirically that doing so matters little (i.e., using parametric tests on ordinal data). The midpoint is often a neutral item, with positive options on one side and negative options on the other. Parametric tests can be carried out with the data collected and analysis of variance test in particular and if it follows normal distribution cycle, 2 sample T-test can be carried out. Likert scale does not tell us that. Step 3: Under "Input Range," select the " Scores range," including the heading.
