INTRODUCTION
Numeracy is referred to as an ability that assists utilisation of mathematics in various
positions and situations by learning, understanding and applying several numerical concepts.
With the help of certain arithmetical concepts such as addition, subtraction (Mohd Nizam,
2019). The temperature of Manchester, UK for 10 sequential days is taken. With this base
several statistical tools as mean, mode and median including the range and standard deviation of
data set are calculated. The Linear Forecasting Model has been used and applied to calculate and
predict future DATE temperatures of day 11 and 14 with the assistance of the data set already
present.

Step1: Segregate and categorise the whole data set.
Step2: Find the addition of all values.
Step3: Find total values in data.
Step4: Perform the division of addition of numbers with total values in the data set.
Mean of the Temperature = Addition of all temperature values in set/ Total number of
values in data set
=> 200 / 10
Mean of the Temperature => 20
Median: This refers to the central positional value of the entire data set in an ascending
or descending arrangement (Klooger, Kalogeropoulos, and Russo, 2022).
Steps for Median calculation:
Step1: Categorise the data set in an ascendant order.
Step2: Examine the data set as even or odd for the total values in it.
Step3: Refer the below formula:
n = If odd : (n+1)th / 2
n = If even : [(n/2)th term + ((n/2)+1)th term] / 2
In this case,
Data set :- 17 18 18 19 19 20 20 22 22 25
Median Value of the temperature (even) = [(n/2) term + ((n/2) + 1) term] / 2
= 10 / 2 term + (10/2+ 1) term / 2
= 5th value + 6th value / 2
= (19 + 20) / 2
Median of the Temperature => 19.5
Mode: the most frequently occurring value from the entire data set.
Steps for Mode calculation:
1: Categorise the given data set in particular order.
2: Tally the number that occurs most number of times.
3: The figure that occurs most in the given data set is its mode.
Data set :- 17 18 18 19 19 20 20 22 22 25

= 10 / 2 term + (10/2+ 1) term / 2
= 5th value + 6th value / 2
= (19 + 20) / 2

Range: It is the difference between the maximum value of the data set and the minimum
value (Austria, and Caringa, 2019).
Steps for Range calculation:
1: Analyse the data.
2: Pick the minimum and maximum value.
3: Find difference between those two numbers.
Computation of Temperature Range
Range of data set = ( Maximum value – Minimum Value )
= (25 - 17)
Range of Temperature => 8
Standard Deviation: It is a statistical tool used to measure and analyse the dispersion of
each value of the data set from the average value of the entire data (Tully, and Gunn, 2019).
Steps for calculation of standard deviation:
1: Assume or calculate the mean value.
2: Find deviation of each value from average.
3: Square the value and take the addition.
4: Divide total of square value from total number of values given.
5: Take square root of the resultant numbers.
Calculation of standard deviation of Temperature:
Standard Deviation = √∑ (xi – μ) ^ 2 / N
=√ (200 – 20) ^ 2 / 10
Standard Deviation for the Temperature = 56.92
4. Calculate the values of 'm' and 'c' and exhibit the use of steps needed. By taking the values of
'm' and 'c', anticipate temperature for day 11 and 14.
Linear Forecasting Model: The main aim of the use of this statistical tool is to analyse,
anticipate and calculate future day values with the help of already existing values. (Andika, and
et.al., 2021)
