Introduction
Quantitative methods in the research paper emphasis on use of mathematical, statical and
performs analysis of data collections techniques such as surveys, questionnaires etc. The
provided technique is useful for the researcher for interpretation of required information to
achieve research aims and objectives. The given report will provide briefings about key issues
covered in class over the previous weeks and will gather SPSS output with a suitable
interpretation (Peytcheva, 2020).
Main Body
Four levels of measurement giving examples of each
Scales of measurement refers to the technique to identify and categorise several variables
for analysis of data in research report. Following are the four levels of measurements; Nominal scale of measurement: Under this level of measurement, property of data is
being evaluated. However, a researcher can't identify or derive any form of numerical
meaning for the given level of measurement. Colour of eye and Region of birth could
possible be example of nominal scale of measurement. Ordinal scale of measurement: For the given scale of measurement defining data that is
placed under a specified order is being taken into consideration. When engaged in value
ranking of data, no information can be displayed that differentiate these data from each
other. For example; satisfaction data points, where; one= neutral, two= happy and three=
unhappy. Interval scale of measurement: Such type of scale of measurement includes data
properties of ordered and nominal data. Under the element difference between points of
data can be done. For example; 50 degrees is not 25 degrees multiplied by 2.
 Ratio scale of measurement: This type of measurement scale, it is composite of all four
scales of measurement. Under this data is defined by possible identities, contai9ns
intervals, classified in order and could be broken down to extract derivatives. Height,
weight and distance are all examples of such measurement.
Measures of Central Tendency and Measures of Dispersion
Qualitative data refers to various measures of central tendency, shape and dispersion. In
other words, central tendency refers to approximate centre of a distribution table also reflected

by mean, median and mode. On the other hand, measures of dispersion refers to degree for which
distribution of data is being distributed around the central tendency. This could be represented by
deviation, range, variance, standard error and standard deviation (Fisher and Bloomfield, 2019).
Measures of Central Tendency
 Arithmetic mean
 Mode
 Median Geometric mean
Measures of Dispersion
 Range
 Percentile
 Deviation
 Variance
Difference between Descriptive Statistics and Inferential Statistics
Basis Descriptive Statistics Inferential Statistics
Population Descriptive Statistics reflects
towards describing target
population.
Inferential Statistics defines
inferences from the sample
and generalise them to the
population.
Presentation of results In form of charts, graphs and
tables.
In form of probability results.
Use Describes data which is
already known to researcher.
Attempts to build on
conclusion by going beyond
the availability of data
(Sheard, 2018).
Explanation The hypothesis and null hypothesis: Null hypothesis is defined as a type of conjecture
which is being used in statistics and proposes which illustrates on displaying no
difference between certain characteristics of data or population. On the other hand,

hypothesis is just an idea which is being proposed for the sake of argument so that
respective objectives of the report can be attained. Independent and dependent variable: Dependent variables are those variables that can't
be manipulated by any other constraint on the other hand independent variable are those
who can bear changes with affect of other variables present.
 Extraneous variables: These are those variables that are no listed in independent variable
but can affect results of the provided experiment (Bloomfield and Fisher, 2019).

Missing Don't know 3 .1
Total 3146 100.0
Interpretation: It has been interpreted from the above mentioned frequency table
cumulative percent of valid very common is 4.7%, fairly common is 12.8% not very common is
48% ant not at all common is 100 %. Along with this, missing don’t have cumulative percent
there is a valid percent i.e. 100. Therefor the total number of frequency is 2146 and percentage is
100.

Interpretation: From the above mentioned Age Grouped Crosstabulation, it has been
interpreted that there are three category of people such as adult (Young), adult and elderly. In
this, 578 are young, 1640 are adult and remaining 916 are elderly. Along with this, majority of
respondents are adults that have accurate knowledge regarding the Noisy neighbours.

Conclusion
From the analysis of above research paper, it can be concluded that, research instrument
plays a crucial role in delivering true value of achievement of desired outcomes. Furthermore, by
interpretation of SPSS results, it can be said that, total percentage of frequency table is 100.
There is highest number of adults i.e. 1640.
