Report: Numeracy and Data Analysis of Bristol Wind Speed, March 2022

This report presents a comprehensive analysis of wind speed data for Bristol, UK, from March 21st to 30th, 2022. The analysis begins with a tabular presentation of the data, followed by the use of two appropriate chart types for visualization. Key statistical measures, including mean, mode, median, range, and standard deviation, are calculated to provide a deeper understanding of the wind speed characteristics. Furthermore, the report employs linear forecasting techniques to predict wind speeds for the 11th and 13th days, demonstrating the practical application of data analysis in forecasting. The report concludes with a summary of the findings and references relevant sources. The calculations of m, c values are also included to show the linear forecasting process.

INTRODUCTION
Data evaluation is the related with having the significant information from the assessing
the presented raw data in turn accomplishing the objective of making strategic decision can
become possible. In the recent time, data numeracy and analysis is highly important as it offers
different form of the efficiency and effectiveness in turn attaining goal of making precise and
information based decision can become possible. The current investigation is based on 10
consecutive days from 21 to 30 march 2022 about Bristol city of UK so that that deeper insights
of the prevailing data can be evaluated. It will focus on showing data in table and having
pictorial presentation of the data set. This will comprise computation of mean, mode, median,
range and SD. Linear equation for computing m, c and wind speed of 11th and 13th days
respectively.

sum 91
Mean 9.1
On the basis of the give table in the above tabular format it can be mentioned that sum
of the data set given for the 10 consecutive days (Bristol Weather, 2022). From the above report
it can be interpreted that mean value is 9.1. This is computed by applying the formula of having
sum of the 10 days wind speed and number of observation.

Mode
This is associated with having the information about the value which is repeated in the
given data set for more than 1. By referring the data set given for the wind speed of Bristol is
having the proper analysis it can be mentioned that the 9 is repeated for 3 times. This repeating
is indicating that this is the mode value of the provided information regarding the wind speed.
Median
It provides assistance in ascertaining centric value of the provided data (Dey and
Wang, 2022). The given information possessing 10 days which are even number so that below
formula will be applied for gaining result.
Formula = n/2 cell + (n/2+1)/2 cell

On the basis of the given information regarding the range it can be mentioned that there
is requirement of ascertaining max and min values. From the assessment of the given
information it can be interpreted that max & min value of the wind speed of the Bristol city is 17
km/hr.
Standard Deviation
It is one of the major tool that is used for gaining the appropriate information about how
he dispersed data is relation to mean (Gong, Wang and Lin, 2021). The lower value indicates
that data is clustered around mean and high shows that data is more spread.

On the basis of the given information it can be mentioned that the data is more spread
out. This play significant role in wind speed forecasting so that appropriate information to
coordinate with the prevailing circumstances can become possible.

Computing m value
m= NΣxy-ΣxΣy/(Σx^2)- (Σx)^2
= (10*542) -(55*91)/10*385- (55) ^2
= (5420-5005)/ (3850-3025)

Determination of c value
c = Σy- mΣx / n
= 91-0.50 (55)/ 10

forecasting wind speed on day 11 and day 13
11th day wind speed determination = mx+ c
= 0.50 (11) +6.334
= 5.5 +6.334
= 11.834
13th day wind speed determination = mx+ c
= 0.50 (13) + 6.334
= 6.5 +6.334
= 12.834
CONCLUSION
From the above report it can be summarized that data analysis is helpful in forecasting
the information in turn taking crucial actions for coordinating with the prevailing circumstances
can become possible. The current report has shown data set of the mentioned period in tabular
manner so that structure format for understanding outcomes. It has been presented in the
pictorial presentation for easy visualization of data. The particular data has mean, mode, median,
range and SD which are 9.1, 9, 9, 17 and 4.323 respectively. The wind speed for the 11th and
13th days are 11.834 & 12.834 km/h which is computed by using the linear equation into the
consideration.
