    How do you perform a quantitative analysis?

    Steps to conduct Quantitative Data Analysis

    1. Relate measurement scales with variables: Associate measurement scales such as Nominal, Ordinal, Interval and Ratio with the variables.
    2. Connect descriptive statistics with data: Link descriptive statistics to encapsulate available data.

    What is quantitative test and qualitative test?

    Qualitative and semi-quantitative examinations are those that give non-numerical results. Qualitative examinations measure the presence or absence of a substance, or evaluate cellular characteristics such as morphology. Semi-quantitative examinations provide an estimate of how much of the measured substance is present.

    What are the statistical tests for quantitative data?

    Statistical tests for quantitative data. You use these to figure out the p-value, i.e. the chance of getting the same results if the null hypothesis were true. There are parametric and non-parametric tests. parametric tests are more accurate, but require the assumption to be made about the data, eg. that the data is normally distributed.

    What is a one sample t-test and how to use it?

    A one sample t-test allows us to test whether a sample mean (of a normally distributed interval variable) significantly differs from a hypothesized value. For example, using the hsb2 data file, say we wish to test whether the average writing score ( write) differs significantly from 50. We can do this as shown below.

    How do you determine if a statistical test is valid?

    For a statistical test to be valid, your sample size needs to be large enough to approximate the true distribution of the population being studied. To determine which statistical test to use, you need to know: whether your data meets certain assumptions. the types of variables that you’re dealing with.

    What criteria are decisive for the selection of the statistical test?

    Three criteria are decisive for the selection of the statistical test, which are as follows: 1 the number of variables, 2 types of data/level of measurement (continuous, binary, categorical) and 3 the type of study design (paired or unpaired). More
