In any research project research main role is collect relevant data from the suitable source. Data gathering is away to provide information for the related topic. Data collection have a various source. In order to collect data there is two specific way to gathering g information. One is primary data where information generate by the questionnaire and books and journals (Jankowicz, 2005). As per this report in data generate through the questionnaire forms. Which are very useful for the research report which the help of primary question data company generate information about the current market problems. On the other hand secondary data is way to generating information through the secondary source of the data collection where information is old which means information is investigated n earlier time and now we use those data in present report. Primary data is first handed data where information through the online questionnaire. Company fill online questionnaire from the respected public in the current market. Furthermore, secondary data is to be generated by the investigators which the help of annual report of the company.

Convenience sampling method : in this sampling method data should be in generate via easily. Most of the researcher are used convenience data methodology because this method of data collection is very easy and understandable by the researcher.

Sample random sampling method: simple random sampling method is a very easy method from all over the above methods of sampling. In this research Blackfriars restaurant use simple random sampling methods where they easy generate information. In this sampling method there is no parameter used. This method is free and randomly determine.

As per the current research report we can use 30 sample size of sampling where used simple Brandon sampling methodology. In this research report research used online questionnaire forms for generating authentic information (Nicholson and Aman, 2012).


2.1 Summarizing collected data

For analysing and research on the company there are different informations and data are required. The data are collected with the help of primary as well as secondary sources and used to analyse regarding business problems. In the present scenario raw data are collected from annual report of the company such as Blackfriars restaurant (Arnicans, 2013). There are mainly two kinds of financial data are derived and summarized which are like as sales or revenue and profit from the FY 2011 to 2017. Further, respective raw data are summarized as below:

Table 1: Raw data for calculation

Raw data for calculation

The above mentioned table shows collected raw data for researching of Blackfriars restaurant and make valid conclusions. Here revenue generated by the restaurant as well as profit level is to determine from the accounting year 2011 to 2017. With the statistical tools such as mean, median and mode the represented raw data are calculated.

2.2 Calculations of mean, median and mode

In the business entity data and analysed using various techniques such as thematic, statistical, mathematical tools etc. In the present case, various kinds of statistical tools and techniques are used such as mean, median as well as mode which are calculated as below:

Table 2: Calculation of mean, median and mode

Calculation of mean, median and mode

  • Mean: The tool which helps to the scholar in order to determine average value of the whole data set is known as mean. When the Blackfriars restaurant wants to know average value of the sales and profit then mean is the best tool. In the present case value of mean for sales and profit is £646 and £173 respectively (Arnold, 2015). On the basis of such outcomes it can be determined that performance of the firm is well.
  • Median: As per the statistical tool, researcher able to know middle value of whole data set and can draw a valid interpretation. Further, it helps to divide overall data into two equal parts when there are huge data in firm. Here middle value of revenue and profit is £658 and £132 which shows that before FY 2015 performance of the firm is poor. After the middle value level sales and profit both are consistently increases.
  • Mode: By using the mean tool management of Blackfriars easily able to know that which data is often occurs in business process. In the current study, sales is not repeated in any year but on the other side profit worth of £125 is repeated in year 2014.

2.3 Computation of standard deviation

Table 3: Calculation of standard deviation

Calculation of standard deviation

Standard deviation: It is a value which shows that real value deviate from mean value up to which extent. Higher the level of difference between mean and standard is better for the firm (Barnes and Duncan, 2013). In the present case standard deviation for sales and profit is £125 and £68 respectively which are so far from the mean value i.e. £646 and £173. Hence, it can be said the Blackfriars is able to perform well in the food industry of London.

2.4 Quartile, percentile and correlation

Measure of dispersions are such as quartile, percentile as well as correlation coefficient which helps to the business entity for determine level of performance. Calculation of different tools of measure of dispersion are stated below:


Calculation of correlation coefficient

Quartile: The tool by which scholar able to divide whole data set in four parts in equal manner. There are three levels of quartile are calculated which are denotes with Q1, Q2 and Q3. At every level value of quartile increase which indicates that performance of the Blackfriars is better in the industry (Measures of Central Tendency and Dispersion. 2013). Value of Q1, Q2 as well as Q3 is worth of £125, £132 and £212 respectively and as level increase the value also raises in the firm.

Correlation coefficient: Another measure of dispersion is correlation coefficient which shows that relationship between two interrelated variables is whether in positive direction or negative. Value of the correlation is always between -1 to +1. In the present case correlation between sales and profit is 0.93 which shows that there are very strong relations among both the variables in Blackfriars restaurant. Hence, it can be said that if sales will increase then it will impact on the level of profit in same direction (Hohna and et.al., 2014).


3.1 Different tools of information processing

  • Transaction processing system: It helps to the Blackfriars restaurant in order to record different kinds of financial transactions in appropriate way (Indiveri and Liu, 2015).

3.2 Assessing financial tools for making business decisions

In the business entity the entrepreneur make investment to generate return and make the firm more profitable. In context to this, there are different financial tools are available which shows that the project will be viable for the firm or not. In the present case, Blackfriars has an option to make investment in second restaurant which is located in London (Milis, 2009). With the help of NPV and IRR calculation of project viability and recommendations are given as below:

Table 7: Calculation of NPV

Calculation of NPV

It can be analysed from the above calculation that when the firm will make investment in second restaurant then it will provide negative return which is worth of -£8567. Apart from this, internal rate of return is also low of the potential investment which is 9.94% at the end of four years. Hence, it can be said that the project or investment is not profitable for Blackfriars restaurant.


On the basis of above discussion it can be suggested to the Blackfriars restaurant that it should not make investment in the second restaurant because it provides negative NPV and lower IRR to the firm.


From the above carried out research on the business decision making it can be concluded that, for collecting primary and secondary data questionnaire and annual report of Blackfriars restaurant is used. Further, performance of the respective restaurant is not better but good in the food industry of London on the basis of various statistical tools and method. It can be concluded from graphical representation that, sales and profit both are reacting in same direction in the firm. Revenue of Blackfriars restaurant is decreases from 2011 to 2013 and then start to increase up to year 2017 and level of profit is as well. It can be analysed as per the financial tools that the investment gives negative return so the firm should not make investment in second restaurant.
