A teacher wanted to know whether it hurts or helps your exam performance if you rethink and change some answers on a multiple-ch

oice test. Students in this study were told to review their final exams and change any answers they wanted to before turning them in. However, the students had to indicate both the original answer and the changed answer for each question. The teacher graded each exam twice, once using the set of original answers and once with the changes. Are the data sufficient to conclude that rethinking and (if necessary) changing your answers has an impact on test scores?

Answer:

Yes, the data are sufficient but...

Explanation:

... only sufficient to conclude that rethinking and changing your answers has an impact on test scores. For example, if I think a little more maybe I come to a different conclusion on this very question I´m answering right now.

But the data given in this example are not sufficient to determine whether rethinking (and changing) hurts or helps.

Frankly I doubt it very much that you can determine such a thing because I feel that for some it will help and for others it will hurt.

Once your business is operational, it's essential to plan and tightly manage its financial performance. Creating a budgeting process is the most effective way to keep your business - and its finances - on track.

This guide outlines the advantages of business planning and budgeting and explains how to go about it. It suggests action points to help you manage your business' financial position more effectively and ensure your plans are practical.

Planning for business success

When you're running a business, it's easy to get bogged down in day-to-day problems and forget the bigger picture. However, successful businesses invest time to create and manage budgets, prepare and review business plans and regularly monitor finance and performance.

Structured planning can make all the difference to the growth of your business. It will enable you to concentrate resources on improving profits, reducing costs and increasing returns on investment.

Even without a formal process, many businesses carry out the majority of the activities associated with business planning, such as thinking about growth areas, competitors, cash flow and profit.

Converting this into a cohesive process to manage your business' development doesn't have to be difficult or time-consuming. The most important thing is that plans are made, they are dynamic and are communicated to everyone involved. See the page in this guide on what to include in your annual plan.

The benefits

The key benefit of business planning is that it allows you to create a focus for the direction of your business and provides targets that will help your business grow. It will also give you the opportunity to stand back and review your performance and the factors affecting your business. Business planning can give you:

a greater ability to make continuous improvements and anticipate problems

sound financial information on which to base decisions

improved clarity and focus

greater confidence in your decision-making

What to include in your annual plan

The main aim of your annual business plan is to set out the strategy and action plan for your business. This should include a clear financial picture of where you stand - and expect to stand - over the coming year. Your annual business plan should include:

an outline of changes that you want to make to your business

potential changes to your market, customers and competition

your objectives and goals for the year

your key performance indicators

any issues or problems

any operational changes

information about your management and people

your financial performance and forecasts

details of investment in the business

Business planning is most effective when it's an ongoing process. This allows you to act quickly where necessary, rather than simply reacting to events after they've happened.

A typical business planning cycle

Review your current performance against last year/current year targets.

Work out your opportunities and threats.

Analyse your successes and failures during the previous year.

Look at your key objectives for the coming year and change or re-establish your longer-term planning.

Identify and refine the resource implications of your review and build a budget.

Define the new financial year's profit-and-loss and balance-sheet targets.

Conclude the plan.

Review it regularly - for example, every month - by monitoring performance, reviewing progress and achieving objectives.

Budgets and business planning

New small business owners may run their businesses in a relaxed way and may not see the need to budget. However, if you are planning for your business's future, you will need to fund your plans. Budgeting is the most effective way to control your cashflow, allowing you to invest in new opportunities at the appropriate time.

If your business is growing, you may not always be able to be hands-on with every part of it. You may have to split your budget up between different areas such as sales, production, marketing etc. You'll find that money starts to move in many different directions through your organisation - budgets are a vital tool in ensuring that you stay in control of expenditure.
