buiness unit 3 part 1 Flashcards
what is a pie chart
a pie chart is a circular chart that is split into sectors that show the percentage or the relative value of different categories of data
what does it show?
it does give a good visual representation of the relative sizes or shares of a whole that can make the different categories of data easier to compare than if the same data was presented in a table
what can it be used to show
-market income
-market share for products or something more specific such as the sales revenue for different types of pizza sold by a pizza chain.
what are the disadvantages of using a pie chart?
pie charts do not give very detailed information, they only give an overall picture of the information presented.
-They are also not effective for showing increases or decreases of proportion over times as trend are not shown and data cannot be extrapolated.
-they also do not show casual relationship such as the impact of advertising spend on sales revenue, meaning that additional information would be needed t support data presented in pie charts.
what are the advantages of using a pie chart?
they could help businesses to make decisions for example if the sales of a specific pizza with a mushroom tuna and pineapple topping had proportionate fewer sales than any other pizza that a business was selling, then they could consider withdrawing the product or promoting it more.
- it does also summarise a large set of data in a visual format
-a lot simpler than other types of graphs
-does display multiple data
what is a bar chart?
a bar chart is another visual way of presenting data. data is usually grouped into categories using rectangular bars with the heigh of the bar representing the frequency for the category.
-bars could be presented vertically or horizontally
-one axis would show the categories compared and the other would show the frequency.
what are the advantages?
would allow the data to be presented in a clear format.
-are useful to summarise a large amount of data in a visual format
-all key values could be highlighted quickly and they are used throughout the business to show financial data
summarize a large data set in visual form.
clarify trends better than do tables.
estimate key values at a glance.
what are the disadvantages of using a bar chart?
- could oversimplify data and further explanations could be needed to give an accurate analysis of data.
-data could also be manipulated to show false results and patterns.
-do fail to reveal key assumptions
-would require additional information
what is a histogram?
a graphical display of data using bars of different heights. Histograms do show qualitative data unlike bar charts. the data in a histogram is continuous so there are no gaps between the bars which represent the different intervals.
what is in a histogram?
area of each bar is proportional to the frequency for each interval. both x axis and y axis do have a scale. in the bar chart the heigh of the bar does indicate the frequency of the category and only the y axis has a numerical scale.
what are the advantages of using a histogram?
does show the shape of the distribution for a large set of data.
- are very good when displaying data that had chronological categories or numerical groupings.
-could also help depict large differences in the shape or symmetry of the data collected.
what are the disadvantages of using a histogram
- cannot be used for exact values as the data is grouped into intervals.
-effectiveness of data does decrease when the range of data is too wide. - data is perhaps less meaningful if the groups are very large
what is a index number?
- it is a data figure that does reflect changes in price or quantity. index numbers would enable users to quickly assess changes in a series of data
how is an index number calculated what is the formula?
a base data value for a specific time is chosen and that is given an index number of 100. subsequent and previous data to the base value can then be converted into index number format.
index number = {value in year b(comparison year)} / value in year a (base year) x 100
what is the formula for income elsacity of demand?
income elasticity of demand = % change in quantity demanded/ % change in income
percentage change = old- new/ old x 100
generally real income increasing over time leading to increased wealth and rising demand for most, but not all good and services. Normally as people get richer, they do consume more driving up demand for many good and services
what is normal good elastic?
(number is greater than 1) positive and high
it would mean that a change in come does cause a more than proportional change in the quantity demanded.
-would resulting in applying to luxury good and services. for example if consumer income decreases then this could result in a fall in cruise holidays or designer handbags.
what is a normal good?
a normal good is inelastic (the number is between 0 and 1). it would mean that a change in come cause a less than proportional change in demand. this would usually be true for necessity good/ services.
-for example fruit and veg
what is an inferior good?
an inferior good is where the number is negative. it would mean that as income does increase, demand would fall and vice versa. example does include own branded goods and public transport.
what would happen if a business is producing inferior goods, with a negative yed?
demand would increase during period of recessions and economic downturn.
-retailers could be advertise their value products. it could be found to attract customers trying to survive on a tight budget.
-if a business does produce an inferior good and economic growth in the long term is positive, they should consider diversifying into producing normal goods.
what does it mean if a business is producing a luxury good, goods with a yes above 1 ( positive and high). and the income is elastic.
-would mean that demand would be sensitive to change in come.
- all high economic growth could lead to a boom in sales but the business should be aware that this boom in sales could core crash to an end if the economy did go into a recession.
-all businesses should be nervous about overstretching themselves. they could also be a case to diversify.
what is sales forecasting?
A sales forecast is an expression of expected sales revenue. A sales forecast estimates how much your company plans to sell within a certain time period (like quarter or year). The best sales forecasts do this with a high degree of accuracy.
what other parts of the business does sales forecast plan the basis of?
human resource plan
production/ capacity plan
break even analysis
profit forecasts and budgets
part of regular competitor analysis and helps to focus on market research
product life cycle
what are the factors that do affect the accuracy and reliability of sales forecasts? sales forecasting does require a subjective judgement about an uncertain future.
consumer trends, if a trend does suddenly emerge sales would increase and sales forecasting would change as there would be a dramatic upward trend in sales.
- however trend are unpredictable and they could suddenly decline or go away for a period of time leading to a dramatic change in sales.
-predication’s could not always be accurate sales forecasting over 3+ years could change a lot over time it would be hard to predict whether sales would change or not as trends could emerge
economic variable could impact sales forecasting by average income, yed, inflation, recession. change in the cost of living can impact as people income decreases sales forecasting would also decrease as less people are in a position to afford products.
- factors such as unemployment growth, trade laws e.g. tariffs, interest rates, exchange rates.
if people income does increase then sales forecasting could also change as more people culd afford products.
competitor actions
competitors could change in the marketing mix.
new disruptors
competitors going under could help
merges and take overs
