Main sources of Data
Transactional
Human
Machine/sensor
Primary Data
Data collected for a specific purpose
Secondary Data
Data already collected elsewhere but can be used for our purposes
Discrete data
Data that is finite
Continuous data
Data that can take on any value within a range
Non production costs
Administrative costs
Finance costs
Selling and distribution
Coding System
A way of expressing the classification of each cost in a shortened symbolised form
Advantages of a coding system
Reduces ambiguity
More suitable than a description in a computerized system

Characteristics of Job costing
Each order has a short duration
Work is undertaken to customers special requirements
It is usual for each job to differ in one or more respects from another job
Identify the costs associated with completing the order
Batch costing
Similar to job costing in that each batch of similar articles is separately identifiable
Cost per unit In batch
Total production cost of batch/number of units in batch
Cost plus pricing
A desired profit margin is added to total costs to arrive at the selling price
Mark up
Calculated as a percentage of the total costs of the job
Process costing
A costing method used where it is not possible to identify separate units of production because of its continuous nature
Average cost per unit
Costs of production/expected or normal output
Formula for normal loss
Average cost per unit =
total costs of inputs - scrap value of normal loss units / units input - normal loss units
Cost Object
Anything to which cost data is desired
Cost unit
A product or service to which costs are ascertained
Cost center
A holding place for costs
Revenue center
Accountable for revenues only
Profit center
Accountable for revenue and costs
Investment center
Accountable for profits and investment responsibilities . Performance will be measured by roce, ri and roi
Random sampling
Each item has an equal chance of being selected
Systematic sampling
Considers every nth of an item
Stratified sampling
Population is divided into subgroups based on characteristics they share, then a random sample is picked from each strata
Number in each sample is proportional to the size of that group in the population and is known as sampling with probability proportional to size
Cluster sampling
Researchers divide the population into multiple groups for research; choosing smaller geographic areas until you get a small enough area
Disadvantages of systematic sampling
Sampling method is not completely random
Sample chosen might be biased
Quota sampling
Investigators are told to interview all the people they meet up to a certain quota
Another name for systematic sampling
Quasi random
Which sampling method should not be used if the population follows a repetitive pattern ?
Systematic sampling
The only non probability sampling method
Quota sampling
Multistage sampling
Draw a sample from the population using smaller and smaller groups at each stage
Advantages of high low method
Easy to use
Easy to understand
Disadvantages of high low method
Requires two extreme points so won’t show average costs in normal periods
Relies on historical data
Assumes activity level is the only factor affecting costs
Bulk discounts may be available at large quantities
Trend line/line of best fit
Straight line which passes through many points on the graph as possible
Extrapolating the trend
Extending the trend line into the future
Disadvantages of using scatter graphs as a forecasting technique
Uses past information to predict future
Assumes relationship is linear
Not accurate
Correlation
Measures the strength between two variables
Formula for correlation
Uses r
Correlation coefficient
Measures the strength of a linear relationship between two variables. It can only take on values between -1 and +1
Coefficient of determination
Measures how much of the variation in the dependent variable is explained by the variation of the independent variable .. denoted by r^2
Advantages of linear regression
Reliable approach to forecasting using Mathematical principles
Can use many data sets so therefore more accurate
Disadvantages of linear regression
Complicated
Only valid when relationships are linear
Uses past data
What does the slope of the regression line tell us
How much change in y variable is caused by a unit change in x variable
Does linear regression assume linear cost behavior
No it just assumes linear relationships
Retail price index
Government produced index to measure general rate of price change in the economy
Time series
A series of values recorded over time
Histogram
Graph of time series
Trend
Underlying movement over time in data values recorded
Seasonal variations
Short term fluctuations in recorded values
Cyclical variations
Medium term fluctuations in data values recorded over time
Residual variations
Random variations; unpredictable, non repetitive
Time series formula
Y = T + S + C + R
Moving average
Average of the results of a fixed number of periods
Two step process in carrying out time series analysis and forecasting
Establishing long term trend
Establishing regular seasonal variation
Advantages of time series analysis
Simple approach
Useful when forecasting data which has a regular seasonal pattern
Disadvantages of time series
Assumes that past trend will continue and extrapolating data based on historic information will give valid conclusions
Sales of products may be influenced by the actions of competitors
Product life cycle
Concept suggesting all products pass through a number of stages from development to decline
Importance of product life cycle in forecasting
When they know what stage a rosy t is in you can market the product more effectively and forecast sales from knowledge on the products current position
Limitations of product life cycle
Difficult to determine precise position of a life cycle
Oversymplistic to assume the curve follows the standard model
Big data
Collection and analysis of large amount s of data
5 v of data
Volume
Variety
Veracity
Velocity
Value
Purchase requisition
Sent from stores to purchase department requesting the materials they want
Purchase order
Sent from company to supplier telling them what they would like to order
Perpetual inventory
Recording inventory as they occur
Periodic stocktaking
Checking the balance of every item in inventory at the end if a period
Continuous stocktaking
Valuing selected items on a rotating basis
Holding costs formula
(Q/2 + buffer inventory) * cost to hold one unit for year
Ordering cost formula
(D/Q) * cost to place one order per year
Stock out costs
Occurs when the business runs out of inventory
Can cause loss of sales, customers, reputation reduced profits
Reorder level
Maximum usage * maximum lead time
Minimum level
Reorder level - (average lead time * average usage)
Maximum level
Reorder level + reorder quantity - (minimum usage * minimum lead time)
Average inventory
Minimum inventory + 1/2 reorder quantity
Periodic weighted average formula
Cost of opening inventory + total costs of receipts/ units of opening inventory + total United received
Direct Labour
Basic pay of direct workers
Indirect Labour costs
Basic pay of indirect workers
Bonus payments
Idle time
Sick pay
Time spent by direct workers doing indirect jobs
What is time and a quarter
1.25
Are overtime premiums tested as direct Labour costs ?
Only at the specific request of the customer
Is premium pay and indirect expense
Yes
